The Company covenants and agrees that it has not taken or permitted to be taken and will not take or permit to be taken any action which will violate the requirements of the Tax Certificate; provided that none of the covenants and agreements herein contained shall require the Company or the Issuer to enter an appearance or intervene in any administrative, legislative or judicial proceeding in connection with any changes in applicable laws, rules or regulations or in connection with any decisions of any court or administrative agency or other governmental body affecting the exclusion from gross income for U.S. federal income tax purposes of interest on the Bonds; and provided further that the Company’s responsibility under this paragraph shall be limited to actions within its control.

The Company recognizes that certain of the facts, estimates and circumstances required to be set forth in the Tax Certificate will be based upon the representations of the Company. The Company covenants to provide, or cause to be provided, such facts, estimates and circumstances as are reasonably necessary to enable the Issuer to execute and deliver the Tax Certificate. The Company further covenants that (a) such facts, estimates and circumstances will be based on the Company’s reasonable expectations on the date of issuance of the Bonds and will be, to the best of the knowledge of the officer or representative of the Company furnishing such facts, estimates and circumstances, true, correct and complete as of that date, and (b) the Company will make reasonable inquiries to insure such truth, correctness and completeness. The Company recognizes that the Trustee will hold and, at the direction of the Company, invest the proceeds of the Bonds within its control in accordance with the expectations of the Issuer set forth in the Tax Certificate.

The Company covenants and agrees that it will not use or permit the use by entities within its control of any of the funds provided by the Issuer hereunder or any other funds of the Company, directly or indirectly, or direct the Trustee to invest any funds held by it hereunder or under the Indenture, in such manner as would, or enter into, or allow any “related person” (as defined in Section 147(a)(2) of the Code) to enter into, any arrangement, formal or informal, for the purchase of the Bonds that would, or take or omit to take any other action that would, to the knowledge of the Company, cause any Bond to be an “arbitrage bond” within the meaning of Section 148 of the Code or “federally guaranteed” within the meaning of Section 149(b) of the Code and applicable regulations promulgated from time to time thereunder. In the event that at any time the Company is of the opinion or is otherwise aware that for purposes of this Section 2.3 it is necessary to restrict or to limit the yield on the investment of any moneys held by the Trustee under the Indenture, the Company shall take such actions as the Company believes are necessary in order to comply with these limitations under the Indenture. The Company covenants to comply with the covenants and procedures set forth in the Tax Certificate and to deposit with the Trustee for rebate to the United States of America any amount which constitutes rebatable arbitrage earnings. The Company will hire, at its own expense, to the extent required, a rebate analyst having the necessary qualifications to calculate any rebatable arbitrage earnings due to the United States of America.

For purposes of complying with their respective obligations under this Section 2.3, the Issuer and the Company may rely upon the advice of nationally recognized bond counsel retained by the Issuer including, but not limited to such advice that is embedded in the Tax Certificate. If the Company becomes aware of any actions or facts which have caused or will cause the interest on the Bonds to be includable in gross income for U.S. federal income tax purposes, the Company promptly shall notify the Trustee, the Issuer and the Remarketing Agent of such actions or facts.

SECTION 2.4. Environmental Representations and Warranties. The Company represents and warrants to the Trustee, the Issuer and the Holders that to the Company’s knowledge and belief, except for matters that would not reasonably be expected to have a Material Adverse Effect:

SECTION 3.2. Disbursements From The Project Fund; Issuance of Bonds.

(a) To provide funds for purposes of financing the cost of the Project, the Issuer will issue, sell and deliver the Bonds upon the order of the Underwriter as provided in the Purchase Agreement. The Bonds will be issued pursuant to the Indenture in the aggregate principal amount, will bear interest, will mature and will be subject to redemption as set forth therein. The Company hereby approves the terms and conditions of the Indenture and the Bonds, and the terms and conditions under which the Bonds will be issued, sold and delivered. The proceeds from the sale of the Bonds shall be paid over to the Trustee for the benefit of the Company and deposited as provided in Section 5.01 of the Indenture and shall be made available to the Company and otherwise applied as provided in the Indenture.

Subject to the provisions below and to the representations, warranties and covenants contained herein and in the Tax Certificate, funds on deposit in the Project Fund, shall be available to be disbursed by the Company only to pay (or to reimburse the Company for payment of) the following Project costs: costs incurred directly or indirectly for or in connection with the development, acquisition, design, engineering, permitting, equipping, construction, installation, improvement, commissioning, start-up and testing of the Project, including, without limitation, costs incurred with respect to the Project and Project Site for preliminary planning and studies; architectural, legal, engineering, accounting, consulting, supervisory and other services; labor, services and materials; and recording of documents and title work; any other incidental and necessary costs, expenses, fees and charges relating to the development, acquisition, design, engineering, permitting, equipping, construction, installation, improvement, commissioning, start-up and testing of the Project.

Funds on deposit in the Costs of Issuance Account of the Project Fund may be applied at any time, as provided in the Indenture, to payment of the following: financial, legal, accounting, consulting, printing and engraving fees, charges and expenses, and all other fees, charges and expenses incurred in connection with the authorization, sale, issuance and delivery of the Bonds, including, without limitation, the fees and expenses of the Issuer, Issuer Counsel and Bond Counsel, the fees and expenses of the Trustee and its counsel, the fees and expenses of counsel to the Company, the fees and expenses of the Remarketing Agent, the fees and expenses of the Credit Facility Provider, if any, and of the Liquidity Facility Provider, if any, and their respective counsel, and the fees and expenses of the Underwriter and its counsel.

Each such written order shall be in the form of the disbursement request attached hereto as Exhibit C and shall be consecutively numbered and accompanied by appropriate documentation supporting the payments or reimbursements requested. The Trustee shall have no duty or obligation to determine whether any such certifications of the Company contained in the disbursement request are correct. In case any contract provides for the retention by the Company of a portion of the contract price, there shall be requested by the Company and paid from the Project Fund only the net amount remaining after deduction of any such portion. Such portion may be requested by the Company and paid from the Project Fund only when such retained amount is due and payable.

The Company covenants, represents and warrants, with respect to any disbursement made to reimburse it for an original expenditure that was paid prior to the date of issuance of the Bonds for which it has been reimbursed from the proceeds of the Bonds, that under Treasury Regulations Section 1.150-2 such disbursement will constitute a reimbursement allocation treated as an expenditure of proceeds of a reimbursement bond for the governmental purpose of the original expenditure on the date of the reimbursement allocation and will be made within the reimbursement period set forth in Treasury Regulations Section 1.150-2(d)(2).

Any moneys in the Project Fund remaining after the Completion Date and payment, or provision for payment, of the costs of the Project described above, at the direction of an Authorized Company Representative, shall promptly be:

(i) used to acquire, construct, equip and improve such additional real or personal property in connection with the Project as is designated by the Authorized Company Representative, and the acquisition, renovation, construction, equipping and installation of which will be permitted under the Act, provided that any such use shall be accompanied by evidence satisfactory to the Trustee that the average reasonably expected economic life of such additional property, together with the other property theretofore acquired with the proceeds of the Bonds, will not be less than 5/6ths of the average maturity of the Bonds, or, if such evidence is not presented with the direction, an opinion of Bond Counsel to the effect that the acquisition of such additional property will not result in the interest on the Bonds becoming subject to federal income taxation;

(ii) used to reimburse the Credit Facility Provider or the Liquidity Facility Provider, if any, for draws or payment on the Credit Facility or the Liquidity Facility, in accordance with the terms of the Indenture;

(iii) used for the purchase of Bonds in the open market for the purpose of cancellation or redemption; or

(iv) used to accomplish a combination of the foregoing as is provided in that direction.

In all cases such moneys remaining after the Completion Date shall be so used or applied only to the extent that, as stated in an opinion of Bond Counsel delivered to the Trustee, such use or application will not adversely affect the exclusion of the interest on the Bonds from gross income for U.S. federal income tax purposes.

In the event that all of the Bonds are either redeemed or accelerated pursuant to the terms of the Indenture, any remaining funds in the Project Fund shall be transferred to the Bond Fund.

SECTION 3.3. Establishment Of Completion Date; Obligation Of Company To Complete.

(b) The Company shall notify the Issuer, any Credit Facility Provider, any Liquidity Facility Facility Provider and the Trustee of the Completion Date by a certificate signed by an Authorized Company Representative stating:

(i) the date on which the Project was substantially completed, which date shall be not later than three years after initial delivery of the Bonds or such later date as will not, in the opinion of Bond Counsel, cause interest on the Bonds to become includable in gross income for U.S. federal income tax purposes;

(ii) that the development, acquisition, design, engineering, permitting, equipping, construction, installation, improvement, commissioning, start-up and testing of the property comprising the Project has been accomplished in such a manner as to conform with all material applicable planning, building, environmental and other similar governmental regulations;

(iii) that except as provided in subsection (iv) of this Section, all material costs of that development, construction, equipping and improvement then or theretofore due and payable have been paid; and

(iv) the amounts which the Trustee shall retain in the Project Fund after substantial completion of the Project for the payment of costs of the Project not yet due or for liabilities which the Company is contesting or which otherwise should be retained and the reasons such amounts should be retained.

That certificate shall state that it is given without prejudice to any rights against third parties which then exist or subsequently may come into being. The certificate shall be delivered as promptly as practicable after the occurrence of the events and conditions referred to in subsections (i) through (iii) of this Section.

The Company hereby covenants that it will restrict that investment and reinvestment and the use of the Bond proceeds in such manner and to such extent, if any, as may be necessary, after taking into account reasonable expectations at the time of delivery of and payment for the Bonds, so that the Bonds will not constitute arbitrage bonds under Section 148 of the Code.

For purposes of complying with their respective obligations under this Section 3.4, the Issuer and the Company may rely upon the advice of nationally recognized bond counsel retained by the Issuer including, but not limited to such advice that is embedded in the Tax Certificate.

SECTION 3.5. Rebate Fund. The Company agrees to make such payments to the Trustee as are required of it under Section 5.12 of the Indenture or as required by this Financing Agreement. The obligation of the Company to make such payments shall remain in effect and be binding upon the Company notwithstanding the release and discharge of the Indenture.

The Company and the Issuer each covenants to the owners of the Bonds that, notwithstanding any other provision of this Financing Agreement or any other instrument, it shall take no action, nor shall the Company direct the Trustee to take or approve the Trustee taking any action or direct the Trustee to make or approve the Trustee’s making any investment or use of proceeds of the Bonds or any other moneys which may arise out of or in connection with this Financing Agreement, the Indenture or the Project, which would cause the Bonds to be treated as “arbitrage bonds” within the meaning of Section 148 of the Code. In addition, the Company covenants and agrees to comply with the requirements of Section 148(f) of the Code as it may be applicable to the Bonds or the proceeds derived from the sale of the Bonds or any other moneys which may arise out of, or in connection with, this Financing Agreement, the Indenture or the Project throughout the term of the Bonds. No provision of this Financing Agreement shall be construed to impose upon the Trustee any obligation or responsibility for compliance with arbitrage regulations.

For purposes of complying with their respective obligations under this Section 3.5, the Issuer and the Company may rely upon the advice of nationally recognized bond counsel retained by the Issuer including, but not limited to such advice that is embedded in the Tax Certificate.

In case the Trustee or the Issuer shall have proceeded to enforce its rights under this Financing Agreement and such proceedings shall have been discontinued or abandoned for any reason or shall have been determined adversely to the Trustee or the Issuer, then, and in every such case, the Company, the Trustee and the Issuer shall be restored respectively to their several positions and rights hereunder, and all rights, remedies and powers of the Company, the Trustee and the Issuer shall continue as though no such action had been taken.

The Company covenants that, in case a Financing Default Event shall occur with respect to the payment of any Financing Payment payable under Section 4.2(a) hereof, then, upon demand of the Trustee, the Company will pay to the Trustee the whole amount that then shall have become due and payable under said Section.

In case the Company shall fail forthwith to pay such amounts upon such demand, the Trustee shall be entitled and empowered to institute any action or proceeding at law or in equity for the collection of the sums so due and unpaid, and may prosecute any such action or proceeding to judgment or final decree, and may enforce any such judgment or final decree against the Company and collect in the manner provided by law the moneys adjudged or decreed to be payable.

In case proceedings shall be pending for the bankruptcy or for the reorganization of the Company under the federal bankruptcy laws or any other applicable law, or in case a receiver or trustee shall have been appointed for the property of the Company or in the case of any other similar judicial proceedings relative to the Company, or the creditors or property of the Company, then the Trustee shall be entitled and empowered, by intervention in such proceedings or otherwise, to file and prove a claim or claims for the whole amount owing and unpaid pursuant to this Financing Agreement and, in case of any judicial proceedings, to file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee allowed in such judicial proceedings relative to the Company, its creditors or its property, and to collect and receive any moneys or other property payable or deliverable on any such claims, and to distribute such amounts as provided in the Indenture after the deduction of its reasonable charges and expenses to the extent permitted by the Indenture. Any receiver, assignee or trustee in bankruptcy or reorganization is hereby authorized to make such payments to the Trustee, and to pay to the Trustee any amount due it for reasonable compensation and expenses, including reasonable expenses and fees of counsel incurred by it up to the date of such distribution.

SECTION 6.3. Agreement To Pay Attorneys’ Fees And Expenses. In the event the Company should default under any of the provisions of this Financing Agreement and the Issuer or the Trustee should employ attorneys or incur other expenses for the collection of the payments due under this Financing Agreement or the enforcement of performance or observance of any obligation or agreement on the part of the Company herein contained, the Company agrees to pay and indemnify the Issuer or the Trustee for the reasonable fees of such attorneys and such other reasonable expenses so incurred by the Issuer or the Trustee.

SECTION 6.4. 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 Financing 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. The Trustee and the Holders of the Bonds shall be considered third party beneficiaries for the purposes of enforcing the rights of the Issuer and their own respective rights.

SECTION 6.5. No Additional Waiver Implied By One Waiver. In the event any agreement or covenant contained in this Financing Agreement should be breached by the Company and thereafter waived by the Issuer or the Trustee, such waiver shall be limited to the particular breach so waived and shall not be deemed to waive any other breach hereunder.

ARTICLE VII
PREPAYMENT

SECTION 7.1. Redemption Of Bonds With Prepayment Moneys. By virtue of the assignment of the rights of the Issuer under this Financing Agreement (other than the Unassigned Issuer’s Rights) to the Trustee as is provided in Section 4.4 hereof, the Company agrees to and shall pay directly to the Trustee any amount permitted or required to be paid by it under this Article VII.

SECTION 7.2. Optional Redemption. The Company may deliver moneys to the Trustee in addition to Financing Payments or Additional Payments required to be made and direct the Trustee to use the moneys so delivered for the purpose of purchasing or redeeming some or all of the Bonds or of reimbursing any Credit Facility Provider, as appropriate, for payments under or drawings on the Credit Facility used to redeem Bonds called for optional redemption in accordance with the applicable provisions of the Indenture. Any moneys delivered by or on behalf of the Company to the Trustee to redeem the Bonds while the Letter of Credit (or any Alternate Credit Facility delivered in substitution thereof) is in effect shall constitute Eligible Funds.

SECTION 7.3. Actions by Issuer. At the request of the Company or the Trustee, the Issuer shall take all reasonable steps required of it under the applicable provisions of the Indenture or the Bonds to effect the redemption of all or a portion of the Bonds pursuant to this Article VII.

SECTION 7.4. Required Deposits for Optional Redemption. Except with the prior written consent of the Credit Facility Provider, if any (except with respect to the optional redemption of Liquidity Provider Bonds), and except as provided in the final paragraph of this Section 7.4, the Trustee shall not give notice of any call to the Holders pursuant to the optional redemption provisions of Section 4.01 of the Indenture and Section 7.2 hereof unless, prior to the date by which the call notice is to be given, there is on deposit with the Trustee moneys sufficient (which shall constitute Eligible Funds so long as the Letter of Credit (or any Alternate Credit Facility delivered in substitution thereof) is in effect) to redeem at the redemption price thereof, including premium (if any) and interest accrued to the redemption date, all Bonds for which notice of redemption is to be given.

All amounts paid by the Company pursuant to this Article which are used to pay principal of, premium, if any, or interest on the Bonds, or to reimburse any Credit Facility Provider for moneys paid or drawn under the Credit Facility and used for such purposes, shall constitute prepaid Financing Payments and shall discharge the Company’s obligation to make Financing Payments in such amount under this Financing Agreement.

Notwithstanding the first sentence of this Section 7.4, the Company may provide that, if at the time of mailing of notice of an optional redemption there shall not have been deposited with the Trustee moneys sufficient to redeem all the Bonds called for redemption, such notice may state that it is conditional (the “Conditional Notice”), subject to the deposit of sufficient moneys (which shall constitute Eligible Funds so long as the Letter of Credit (or any Alternate Credit Facility delivered in substitution thereof) is in effect) with the Trustee not later than the opening of business on the scheduled redemption date, and such Conditional Notice shall be of no effect unless such moneys are so deposited. In the event sufficient moneys (which shall constitute Eligible Funds so long as the Letter of Credit (or any Alternate Credit Facility delivered in substitution thereof) is in effect) are not on deposit on the required date, then the redemption shall be cancelled and on such cancellation date notice, prepared by and at the expense of the Company, shall be provided to the Holders in the same manner as the Conditional Notice was provided, and the failure to redeem the Bonds on such date shall not constitute a Financing Default Event hereunder.

SECTION 7.5. Purchase of Bonds in Lieu of Redemption. Pursuant to Section 4.07 of the Indenture, the Company shall have the right to purchase Bonds called for redemption pursuant to Section 4.01 of the Indenture, in lieu of such redemption, at a purchase price equal to the applicable redemption price, plus accrued interest to the purchase date (which purchase date shall be the date such Bonds would otherwise have been redeemed in accordance with the applicable provisions of Section 4.01 of the Indenture).

No purchase of Bonds pursuant to Section 4.07 of the Indenture by the Company shall be deemed to be a prepayment of the amounts due from the Company hereunder or of any portion thereof. Such purchase shall not operate to extinguish or discharge this Financing Agreement.

ARTICLE VIII
NON-LIABILITY OF ISSUER; EXPENSES; INDEMNIFICATION

SECTION 8.1. Non-Liability Of Issuer. The Issuer shall not be obligated to pay the principal of, Purchase Price or premium, if any, or interest on the Bonds, except from Revenues. The Company hereby acknowledges that the Issuer’s sole source of moneys to repay the Bonds will be provided by the payments made by the Company pursuant to this Financing Agreement, together with other Revenues, including investment income on certain funds held by the Trustee under the Indenture, and hereby agrees that if the payments to be made hereunder shall ever prove insufficient to pay all principal of, and premium, if any, and interest on the Bonds as the same shall become due (whether by maturity, redemption, acceleration or otherwise), then upon notice from the Trustee, the Company shall pay such amounts as are required from time to time to prevent any deficiency or default in the payment of such principal, premium or interest, including, but not limited to, any deficiency caused by acts, omissions, nonfeasance or malfeasance on the part of the Trustee, the Company, the Issuer or any third party.

SECTION 8.2. Expenses. The Company covenants and agrees to pay and to indemnify the Issuer and the Trustee against all costs and charges, including reasonable fees and disbursements of attorneys, accountants, consultants and other experts, incurred in good faith in connection with this Financing Agreement, the Bonds or the Indenture.

SECTION 8.3. Indemnification. (a) The Company releases the Trustee from, and covenants and agrees that the Trustee shall not be liable for, and covenants and agrees, to the extent permitted by law, to indemnify and hold harmless the Trustee and its members, officers, employees and agents from and against, any and all losses, claims, damages, liabilities or expenses (including, without limitation, reasonable attorneys’ fees, litigation and court costs, amounts paid in settlement and amounts paid to discharge judgments), of every conceivable kind, character and nature whatsoever (including, without limitation, federal and state securities laws) arising out of, resulting from or in any way connected with (1) the Project, or the conditions, occupancy, use, possession, conduct or management of, or work done in or about the Project or the other facilities of the Company or its Affiliates, or from the planning, design, acquisition, construction, rehabilitation, renovation, improvement, installation or equipping of the Project or any part thereof; (2) the issuance, sale or resale of any Bonds or any certifications or representations made in connection therewith, the execution and delivery of this Financing Agreement, the Indenture or the Tax Certificate or any amendment thereto and the carrying out of any of the transactions contemplated by the Bonds, the Indenture and this Financing Agreement; (3) the Trustee’s acceptance or administration of the trusts under the Indenture, or the exercise or performance of any of their powers or duties under the Indenture or this Financing Agreement; (4) any untrue statement or alleged untrue statement of any material fact or omission or alleged omission to state a material fact required to be stated or necessary to make the statements made, in light of the circumstances under which they were made, not misleading, in any official statement or other offering circular utilized by any underwriter or placement agent in connection with the sale or remarketing of any Bonds or in any disclosure made by Company to comply with the requirements of S.E.C. Rule 15c2-12; (5) any violation of any Environmental Requirements or the release of any Hazardous Substance at, from, under or on the Project or any other facilities owned or operated by the Company or its Affiliates; (6) the defeasance and/or redemption, in whole or in part, of the Bonds; or (7) any declaration of taxability of interest on the Bonds, or allegations that interest on the Bonds is taxable or any regulatory audit or inquiry regarding whether interest in the Bonds is taxable; provided that such indemnity shall not be required for damages that result from the negligence or willful misconduct on the part of the party seeking such indemnity. The Company further covenants and agrees, to the extent permitted by law, to pay or to reimburse the Trustee and its officers, employees and agents for any and all costs, reasonable attorneys’ fees and expenses, liabilities or other expenses incurred in connection with investigating, defending against or otherwise in connection with any such losses, claims, damages, liabilities, expenses or actions, except to the extent that the same arise out of the negligence or willful misconduct of the Trustee and its officers, employees and agents claiming such payment or reimbursement. The provisions of this Section and Section 4.2(b) shall survive any resignation or removal of the Trustee, the retirement of the Bonds and the termination of this Financing Agreement.

(b) The Company will, to the fullest extent permitted by law, protect, indemnify and save the Issuer and the State and their officers, agents, and employees and any person who controls the Issuer within the meaning of the Securities Act of 1933, harmless from and against all liabilities, losses, damages, costs, expenses (including attorneys’ fees and expenses of the Issuer), taxes, causes of action, suits, claims, demands and judgments in connection with the transaction contemplated by this Financing Agreement or arising from or related to the issuance or sale of the Bonds, including but not limited to:

(i) any injury to or death of any person or damage to property in or upon the Project or growing out of or connected with the use, non-use, condition or occupancy of the Project or any part thereof, including any and all acts or operations relating to the acquisition or installation of property or improvements. The foregoing indemnification obligations shall not be limited in any way by any limitation on the amount or type of damages, compensation or benefits payable by or for the Company, customers, suppliers or affiliated organizations under any Workers’ Compensation Acts, Disability Benefit Acts or other employee benefit acts;

(ii) violation of any agreement, provision or condition of this Financing Agreement, the Bonds or the Indenture, except a violation by the party seeking indemnification;

(iii) violation by the Company of any contract, agreement or restriction which shall have existed at the commencement of the term of this Financing Agreement or shall have been approved by the Company;

(iv) violation by the Company of any law, ordinance, court order or regulation affecting the Project or a part thereof or the ownership, occupancy or use thereof;

(v) any statement or information relating to the expenditure of the proceeds of the Bonds contained in the Tax Certificate or similar document furnished by the Company to the Issuer or Trustee which, at the time made, is misleading, untrue or incorrect in any material respect; and

(vi) any untrue statement or alleged untrue statement of a material fact contained in any offering material relating to the sale of the Bonds (as from time to time amended or supplemented) or arising out of or based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary in order to make the statements therein not misleading, or failure to properly register or otherwise qualify the sale of the Bonds or failure to comply with any licensing or other law or regulation which would affect the manner whereby or to whom the Bonds could be sold.

Promptly after receipt by the Issuer or any such other indemnified person, as the case may be, of notice of the commencement of any action with respect to which indemnity may be sought against the Company under this Section, such person will notify the Company in writing of the commencement thereof, and, subject to the provisions hereinafter stated, the Company shall assume the defense of such action (including the employment of counsel, who shall be counsel subject to the approval of the indemnified person, which approval shall not be unreasonably withheld, and the payment of expenses). Insofar as such action shall relate to any alleged liability with respect to which indemnity may be sought against the Company, the Issuer, the Trustee or any such other indemnified person shall have the right to employ separate counsel of their own choice in any such action and to participate in the defense thereof, and the fees and expenses of such counsel shall be at the expense of the Company. The Company shall not settle or compromise any action or proceeding defended by the Company without the express written consent of the affected party, unless such settlement or compromise (x) includes an unconditional release of the affected party from all liability arising out of such action or proceeding and (y) does not include a statement or admissions of fault, culpability or a failure to act, by or on behalf of, the affected party. The Company shall not be liable for any settlement of any such action effected without its consent, but if any action is settled with the consent of the Company or if there be a final judgment for the plaintiff in any such action, the Company shall indemnify and hold harmless each indemnified party from and against any losses, claims, damages, liabilities or expenses incurred or suffered by reason of such settlement or judgment.

The provisions of this Section shall survive payment and discharge of the Bonds. If the Trustee resigns or is replaced, the Company’s obligations under this Section 8.3 shall continue for the benefit of the Trustee as well as the successor Trustee.

The Issuer shall not be liable for any costs, expenses, losses, damages, claims or actions, of any conceivable kind on any conceivable theory, under or by reason of or in connection with this Financing Agreement, the Bonds or the Indenture, except only to the extent amounts are received for the payment thereof from the Company under this Financing Agreement.

The Company hereby acknowledges that the Issuer’s sole source of moneys to repay the Bonds will be provided by the payments made by the Company to the Trustee pursuant to this Financing Agreement, together with investment income on certain funds held by the Trustee under the Indenture, and hereby agrees that if the payments to be made hereunder shall ever prove insufficient to pay all principal (or redemption price) and interest on the Bonds as the same shall become due (whether by maturity, redemption, acceleration or otherwise), then upon notice from the Trustee, the Company shall pay such amounts as are required from time to time to prevent any deficiency or default in the payment of such principal (or redemption price) or interest, including, but not limited to, any deficiency caused by acts, omissions, nonfeasance or malfeasance on the part of the Trustee, the Company, the Issuer or any third party, subject to any right of reimbursement from the Trustee, the Issuer or any such third party, as the case may be, therefor.

The provisions of this Section shall be in addition to, and not in lieu of, any other provisions limiting the liability of the Issuer hereunder.

SECTION 10.13. Waiver of Personal Liability. No member, officer, agent or employee of the Issuer or any director, officer, agent or employee of the Company shall be individually or personally liable for the payment of any principal (or redemption price) or interest on the Bonds or any sum hereunder or under the Indenture be subject to any personal liability or accountability by reason of the execution and delivery of this Financing Agreement; but nothing herein contained shall relieve any such member, director, officer, agent or employee from the performance of any official duty provided by law or by this Financing Agreement.

SECTION 10.14. No Constitutional Debt. It is understood and agreed by the Company and the Bondowners that no covenant, provisions or agreement of the Issuer herein or in the Bonds or in any other document executed by the Issuer in connection with the issuance, sale and delivery of the Bonds, or any obligation herein or therein imposed upon the Issuer or breach thereof, shall give rise to a pecuniary liability of the Issuer, its directors, officers, employees or agents or a charge against the Issuer’s general credit or general fund or shall obligate the Issuer, its directors, officers, employees or agents financially in any way except with respect to the Indenture, the funds and accounts held thereunder and the application of revenues therefrom and from this Financing Agreement, and from the proceeds of the Bonds. No failure of the Issuer to comply with any term, condition, covenant or agreement herein or in the Indenture shall subject the Issuer, its directors, officers, employees or agents to liability for any claim for damages, costs or other financial or pecuniary charges except to the extent that the same can be paid or recovered from the Indenture, the funds and accounts held thereunder and the application of revenues therefrom and from this Financing Agreement and from the proceeds of the Bonds. No execution on any claim, demand, cause of action or judgment shall be levied upon or collected from the general credit or general fund of the Issuer. In making the agreements, provisions and covenants set forth herein, the Issuer has not obligated itself except with respect to the Indenture and the funds and accounts held thereunder and the application of revenues therefrom and from this Financing Agreement, and from the proceeds of the Bonds, as hereinabove provided.

The Bonds constitute special, limited obligations of the Issuer, payable solely from proceeds of the Bonds, draws under the Credit Facility or Liquidity Facility, the revenues pledged to the payment thereof pursuant to this Financing Agreement, and the funds and accounts held under and pursuant to the Indenture and pledged therefor. The Bonds, the interest thereon and any other payments or costs incident thereto do not constitute an indebtedness or a loan of the credit of the Issuer, the State of Iowa or any political subdivision thereof within the meaning of any constitutional or statutory provisions. The Issuer does not pledge its faith or credit nor the faith or credit of the State nor any political subdivision of the State to the payment of the principal of, the interest on or any other payments or costs incident to the Bonds. The issuance of the Bonds and the execution of any documents in relation thereto do not directly, indirectly or contingently obligate the State or any political subdivision of the State to apply money from or levy or pledge any form of taxation whatever to the payment of the principal of or interest on the Bonds or any other payments or costs incident thereto. The Issuer has no taxing power.

It is further understood and agreed by the Company and the Bondowners that the Issuer, its directors, officers, employees or agents shall incur no pecuniary liability hereunder and shall not be liable for any expenses related hereto, all of which the Company agrees to pay. If, notwithstanding the provisions of this Section, the Issuer, its directors, officers, employees or agents incur any expense, or suffer any losses, claims or damages or incurs any liabilities, the Company will indemnify and hold harmless the Issuer, its directors, officers, employees or agents from the same and will reimburse the Issuer, its directors, officers, employees or agents in relation thereto, and this covenant to indemnify, hold harmless and reimburse the Issuer, its directors, officers, employees or agents shall survive payment and discharge of the Bonds.

SECTION 10.15. Annual Information for Audit. Company agrees that it will annually on or before August 15 of each year furnish the Issuer with a statement of the principal amount of the Bonds outstanding as of the immediately preceding June 30. In addition, the Company shall provide the Issuer with any other information which may from time to time be requested concerning the Bonds according to the rules and interpretations of the Governmental Accounting Standards Board required to be disclosed concerning conduit debt obligations.

SECTION 10.16. Complete Agreement. The parties agree that the terms and conditions of this Financing Agreement supersede those of all previous agreements between the parties relative to the Bonds, and that this Financing Agreement, together with the documents referred to in this Financing Agreement, contains the entire agreement relative to the Bonds between the parties hereto.
