The Company agrees that at no time shall any funds constituting gross proceeds of the Bonds be used in any manner to cause or result in a prohibited payment under applicable regulations pertaining to, or in any other fashion as would constitute failure of compliance with, Section 148 of the Code. If there is any amount required to be paid to the United States pursuant to Section 148(f) of the Code or Section 5.03 of the Indenture, the Company shall pay such amount to the Trustee for deposit to the Rebate Fund created under Section 5.03 of the Indenture, who will, acting on behalf of the Company, submit the payment to the United States. 9

Such proceeds shall be disbursed to or on behalf of the Company as provided in Section 3.02. On each date on which any payment of principal or redemption price of, or interest on, the Bonds shall become due (whether at maturity, or upon redemption or acceleration or otherwise), the Company will pay or cause to be paid to the Trustee, in immediately available funds, an amount which, together with other moneys held by the Trustee under the Indenture and available therefor, will enable the Trustee to make such payment of principal or redemption price of, of or interest on, the Bonds to the Bondholders in full in a timely manner (“Installment Payments”). In furtherance of the foregoing, so long as any Bonds are outstanding, the Company will pay or cause to be paid all amounts required to prevent any deficiency or default in any payment of principal or redemption price of, or interest on, the Bonds, including any deficiency caused by an act or failure to act by the Trustee, the Company, the Issuer or any other Person.

Such deposits shall be credited against the Installment Payments, or any portion thereof, in the order of their due dates. Such deposits shall not in any way alter or suspend the obligations of the Company under this Agreement during the term hereof as provided in Section 10.01. In addition, the Company may deliver moneys to the Trustee for use for optional redemption of Bonds pursuant to Sections 6,01 and 6.02 and shall deliver moneys to the Trustee for mandatory redemption of Bonds as required by Section 4.02(b)(ii) of the Indenture.

without limitation, any defense (other than payment), setoff, recoupment or counterclaim which the Company may have or assert against the Issuer, the Trustee or any other Person. Section 4.05. Assignment by Company. Rights granted to the Company under this Agreement may be assigned in whole or in part by the Company without the necessity of obtaining the consent of the Issuer or the Trustee, subject, however, to each of the following conditions: (a) unless waived by the Issuer or the Trustee, the Company shall notify the Issuer and the Trustee in writing of the identity of any assignee at least 30 days prior to the effective date of such assignment; (b) no assignment shall relieve the Company from primary liability hereunder for its obligations hereunder, and the Company shall continue to remain primarily liable for the payment of the Installment Payments and Additional Payments and for performance and observance of the agreements on its part herein provided to be performed and observed by it; (c) any assignment from the Company must retain for the Company such rights and interests as will permit it to perform its obligations under this Agreement; (d) the Company shall, within 30 days after the execution thereof, furnish or cause to be furnished to the Issuer and the Trustee a true and complete copy of each such assignment; and (e) any assignment from the Company shall not materially impair fulfillment of the purposes to be accomplished by operation of the Project Facilities as a project, the refinancing of which is permitted under the Act.

ARTICLE V ADDITIONAL AGREEMENTS AND COVENANTS Section 5.01. Lease, Sale or Grant of Use by Company. Subject to the provisions of Section 5.03, the Company may lease, sell or grant the right to occupy and use the Project Facilities, in whole or in part, to others, provided that: (a) no such grant, sale or lease shall relieve the Company from its obligations under this Agreement; (b) the Company shall retain such rights and interests as will permit it to comply with its obligations under this Agreement; 12

(c) no such grant, sale or lease shall impair the purposes of the Act; and (d) the Company shall receive an Opinion of Nationally Recognized Bond Counsel that such grant, sale or lease does not have an adverse effect upon the tax-exempt status of the Bonds. Section 5.02. Indemnification of Issuer and Trustee. The Company agrees that the Issuer, the State and their respective members, officers, employees and agents, and the Trustee and the Tender Agent and each of its officers, employees and agents, shall not be liable for, and the Company covenants and agrees to protect, exonerate, defend, indemnify and save the Issuer, the State and their respective members, officers, employees and agents, and the Trustee and its officers, employees and agents, harmless from and against (a) any and all costs, damages or liabilities which may arise out of the issuance of the Bonds, the refinancing of the Project Facilities or any breach or default on the part of the Company to be performed pursuant to the terms of this Agreement and (b) all reasonable costs, counsel fees, expenses and liabilities incurred in or about the defense of any such claims or actions or proceedings brought thereon; except in any case with respect to (1) the Issuer, the State and their respective members, officers, employees and agents as a result of the gross negligence or willful misconduct of the Issuer, the State and such respective members, officers, employees and agents and (2) the Trustee and its officers, employees and agents as a result of the negligence or willful misconduct of the Trustee or such officers, employees or agents. The Company may, at its cost and in its name or in the name of the Issuer or the Trustee, as the case may be, prosecute or take any other action involving third persons which the Company deems necessary in order to ensure or protect the Company’s rights under this Agreement; in such event, the Issuer or the Trustee, as the case may be, will reasonably cooperate with the Company, but at the sole expense of the Company. The Company agrees to indemnify the Trustee and the Issuer for and to hold each of them harmless against all liabilities, claims, court costs and reasonable and documented out-of-pocket expenses (including reasonable and documented fees and expenses of counsel necessary in defending against the same) incurred without gross negligence or willful misconduct on the part of the Issuer or incurred without negligence or willful misconduct on the part of the Trustee, as applicable, on account of any action taken or omitted to be taken by the Issuer or the Trustee, as applicable, in accordance with the terms of this Agreement, the Bonds or the Indenture or any action taken at the request of or with the consent of the Company, including the costs and expenses of the Issuer and the Trustee, as applicable, in defending itself against any such claim, action or proceeding brought in connection with the exercise or performance of any of its powers or duties under this Agreement, the Bonds or the Indenture. In case any actions or proceeding is brought against the Issuer or the Trustee in respect of which indemnity may be sought hereunder, the party seeking indemnity shall promptly (but in any event within 15 days of receipt of service) give notice of that action or proceeding to the Company enclosing copies of all papers served, and the Company upon receipt of that notice shall have the obligation and the right to assume the defense of the action or proceeding; provided, that failure of a party to give that notice shall not relieve the Company from any of its obligations under this Section unless that failure materially prejudices the defense of the action or proceeding by the Company. An indemnified party may employ separate counsel and participate in the defense thereof, and the Company shall pay the reasonable fees and expenses of such separate counsel; 13

provided, however, that an indemnified party may only employ separate counsel at the expense of the Company if in the reasonable, good faith judgment of such indemnified party (i) a conflict of interest exists by reason of common representation or (ii) there are legal defenses available to such indemnified party that are different from or are in addition to those available to the Company or another indemnified party or if all parties commonly represented do not agree as to the action (or inaction) of counsel. Such indemnified party agrees to give the Company prior written notice of any determination that such a conflict exists and that it intends to retain separate counsel. The Company shall not be liable for any settlement of any such action or proceeding effected without its written consent (which shall not be unreasonably withheld or delayed), but if settled with the consent of the Company, or if there be a final judgment for the plaintiff in any such action, the Company agrees to indemnify and hold harmless any such indemnified party from and against any loss or liability by reason of such settlement or judgment. Notwithstanding anything contained herein to the contrary, the Company shall not be obligated to indemnify or hold harmless the Issuer, the State or their respective members, officers, employees and agents for their gross negligence or willful misconduct (as finally determined by a court of competent jurisdiction) or the Trustee or its officers, employees and agents for their negligence or willful misconduct. The foregoing indemnification is intended to and shall include the indemnification of all affected officials, directors, trustees, officers, employees and agents of the Issuer and the Trustee, respectively. That indemnification is intended to and shall be enforceable by the Issuer and the Trustee, respectively, to the full extent permitted by law, and the foregoing indemnification shall survive beyond the termination or discharge of the Indenture or payment of the Bonds. Section 5.03. Company Not to Adversely Affect Exclusion from Gross Income of Interest on Bonds. The Company hereby represents that it has taken and caused to be taken, and covenants that it will take and cause to be taken, all actions that may be required of it, alone or in conjunction with the Issuer, for the interest on the Bonds to be and to remain excludable from gross income for federal income tax purposes, and represents that it has not taken or permitted to be taken on its behalf, and covenants that it will not take or permit to be taken on its behalf, any action that would adversely affect such excludability under the provisions of the 1954 Code or the Code, as applicable. The Company also covenants that it will restrict the investment and reinvestment and the use of the proceeds of the Bonds in such manner and to such extent, if any, as may be necessary so that the Bonds will not constitute arbitrage bonds under Section 148 of the Code. The Company hereby covenants that on or before the 90th day following the date any of the Project Facilities are no longer being operated as qualifying exempt facilities under the Code (unless such facilities have simply ceased to be operated), or such later date as provided in the Indenture, the Company shall cause a related amount of Bonds to be redeemed pursuant to the Extraordinary Mandatory Redemption provision of the Bonds as provided in Section 4.02(b)(ii) of the Indenture. Section 5.04. Company to Maintain its Existence; Mergers or Consolidations. The Company covenants that it will not merge or consolidate with any other legal entity or sell or 14

convey all or substantially all of its assets to any other legal entity, except that the Company may merge or consolidate with, or sell or convey all or substantially all of its assets to any other legal entity, provided that (a) the Company shall be the continuing legal entity or the successor legal entity (if other than the Company) shall be a legal entity organized and existing under the laws of the United States of America or a state thereof, qualified to do business in the State, and such legal entity shall expressly assume the due and punctual payment of the Installment Payments and the Additional Payments hereunder in order to ensure timely and proper payment of the principal of and interest on all the Bonds, according to their tenor, and the due and punctual performance and observance of all the covenants and conditions of this Agreement to be performed by the Company (an “Assumption Agreement”) and (b) the Company or such successor legal entity, as the case may be, shall not, immediately after such merger or consolidation, or such sale or conveyance, be in default in the performance of any such covenant or condition and no event which with the lapse of time, the giving of notice or both would constitute an Event of Default under Section 7.01 shall have occurred and be continuing. The Company shall, within 30 days after the execution of an Assumption Agreement, furnish to the Issuer and the Trustee an executed copy of such Assumption Agreement and appropriate documentation demonstrating that the successor legal entity (if other than the Company) is organized and existing under the laws of the United States of America or a state thereof and is qualified to do business in the State. In the case of any such consolidation, merger, sale or conveyance and upon the assumption by the successor legal entity of the obligations under this Agreement and on the Bonds in accordance with the foregoing, such successor legal entity shall succeed to and be substituted for the Company, with the same effect as if it had been named herein as a party hereto, and the Company shall thereupon be relieved of any further obligations or liabilities hereunder and upon the Bonds and the Company as the predecessor legal entity may thereupon or at any time thereafter be dissolved, wound-up or liquidated. Section 5.05. Reports and Audits. The Company shall as soon as practicable but in no event later than six months after the end of each of its fiscal years, file with the Trustee and the Issuer, audited financial statements of the Company prepared as of the end of such fiscal year; provided that the Company may satisfy this requirement by its filing of such information with the Securities and Exchange Commission (xxx.xxx.xxx) and the Municipal Securities Rulemaking Board (xxx.xxxx.xxxx.xxx) in accordance with their respective filing requirements, and the Trustee's receipt of such shall not constitute actual or constructive notice or knowledge of any information contained therein or determinable from information contained therein, including the Company's compliance with any of its covenants hereunder. The Trustee shall have no duty to review such financial statements, shall be deemed to have actual or constructive notice or knowledge of any information contained therein or determinable from information contained therein, including the Company’s compliance with any of its covenants hereunder or whether any default or Event of Default may have occurred, and the Trustee shall not have any duty to verify the accuracy of such financial statements or any portion thereof. Section 5.06. Insurance. The Company shall maintain, or cause to be maintained, insurance covering the Project Facilities against such risks and in such amounts as is customarily 15

carried by similar industries as the Company, and which insurance may be, in whole or in part, self- insurance. Section 5.07. Company to Furnish Notices and Opinions Relating to Changes in Interest Rate Periods. The Company is hereby granted the option to designate from time to time changes in Interest Rate Periods in the manner and to the extent set forth in Section 2.03 of Exhibit B 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 Interest Rate Periods to be given in accordance with the provisions of Section 2.03 of Exhibit B of the Indenture and to deliver any Opinions of Nationally Recognized Bond Counsel required under the Indenture in connection therewith. ARTICLE VI OPTIONS; PREPAYMENT OF INSTALLMENT PAYMENTS Section 6.01. Options to Terminate Agreement.

Any prepayment pursuant to this Section shall either comply with the provisions of Article IX of the Indenture or result in redemption of the Bonds within 90 days of the date of prepayment. Nothing contained in this Section shall prevent the payment of part of any of the Bonds pursuant to Article IV or Section 9.02 of the Indenture. Section 6.02. Option to Prepay Installment Payments upon Extraordinary Optional Redemption under Indenture.

Upon the payment of all amounts due hereunder and under the Indenture pursuant to any option or obligation to prepay the Installment Payments in full as provided in this Agreement, the Issuer shall, upon receipt of the prepayment by the Trustee, deliver to the Company, if necessary, a release from the Trustee of the lien of the Indenture. ARTICLE VII EVENTS OF DEFAULT AND REMEDIES Section 7.01. Events of Default. Each of the following shall be an Event of Default: (a) The Company shall fail to pay the amounts required to be paid under Section 4.01 or 4.02 on the date specified therein. (b) Failure by the Company to observe and perform any covenant, condition or agreement on its part to be observed or performed under this Agreement, other than as referred to in Section 7.01(a), (other than certain representations, warranties and covenants regarding various matters relating to the tax status of the interest on the applicable series of Bonds) for a period of 60 days after written notice specifying such failure and requesting that it be remedied shall have been given to the Company by the Issuer or the Trustee, unless the Issuer and the Trustee (acting at the written direction of the holders of a majority in aggregate principal amount of the Outstanding Bonds) 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, it shall not constitute an Event of Default if corrective action is instituted by the Company within the applicable period and is being diligently pursued until the default is corrected. (c) The dissolution or liquidation of the Company or the voluntary initiation by the Company of any proceeding under any federal or state law relating to bankruptcy, insolvency, arrangement, reorganization, readjustment of debt or any other form of debtor relief, or the initiation against the Company of any such proceeding which shall remain undismissed for 60 days, or failure by the Company to promptly have discharged any execution, garnishment or attachment of such consequence as would materially impair the ability of the Company to carry on its operations, or assignment by the Company for the benefit of creditors, or the entry by the Company into an agreement of composition with creditors or the failure generally by the Company to pay its debts as they become due. (d) The occurrence of an Event of Default as defined in the Indenture. Any declaration of default under subparagraph (c) and the exercise of remedies upon any such declaration will be subject to any applicable limitations of federal bankruptcy law affecting or 17

precluding that declaration or exercise during the pendency of or immediately following any bankruptcy, liquidation or reorganization proceedings. Section 7.02. Remedies on Default. Whenever an Event of Default shall have happened and be existing, any one or more of the following remedial steps may be taken: (a) if acceleration of the principal amount of a series of Bonds has been declared pursuant to Section 7.03 of the Indenture, the Issuer or the Trustee shall declare all Installment Payments to be immediately due and payable, whereupon the same shall become immediately due and payable; or (b) the Issuer or the Trustee may pursue all remedies now or hereafter existing at law or in equity to collect all amounts then due and thereafter to become due under this Agreement or to enforce the performance and observance of any other obligation or agreement of the Company under those instruments. Notwithstanding the foregoing, the Trustee shall not be obligated to take any step that in its reasonable opinion will or might cause it to expend time or money or otherwise incur liability unless and until satisfactory indemnity has been furnished to the Trustee at no cost or expense to it. Any amounts collected pursuant to action taken under this Section (except for amounts payable directly to the Issuer or the Trustee pursuant to Section 3.05, 4.02, 5.02 or 7.04) shall be paid into the Bond Fund and applied in accordance with the provisions of the Indenture or, if the Outstanding Bonds have been paid and discharged in accordance with the provisions of the Indenture, shall be paid as provided in Section 9.01 of the Indenture for transfers of remaining amounts in the Bond Fund. The provisions of this Section are subject to the further limitation that the rescission by the Trustee of its declaration that all of the Bonds are immediately due and payable also shall constitute an annulment of any corresponding declaration made pursuant to paragraph (a) of this Section and a waiver and rescission of the consequences of that declaration and of the Event of Default with respect to which that declaration has been made, provided that no such waiver or rescission shall extend to or affect any subsequent or other default or impair any right consequent thereon. Section 7.03. No Remedy Exclusive. No remedy conferred upon or reserved to the Issuer or the Trustee by this Agreement is intended to be exclusive of any other available remedy or remedies, but each and every remedy shall be cumulative and shall be in addition to every other remedy given under this Agreement, now or hereafter existing at law, in equity or by statute. No delay or omission to exercise any right or power accruing upon any default shall impair that 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 any notice required by law or for which express provision is made herein. Section 7.04. Agreement to Pay Fees and Expenses. If an Event of Default should occur and the Issuer or the Trustee should incur expenses, including attorneys’ fees, in connection with the enforcement of this Agreement or the collection of sums due hereunder, the Company shall reimburse the Issuer and the Trustee, as applicable, for their reasonable and documented out-of- pocket expenses so incurred upon demand. 18

Section 7.05. No Waiver. No failure by the Issuer or the Trustee to insist upon the performance by the Company of any provision hereof shall constitute a waiver of their right to performance and no express waiver shall be deemed to apply to any other existing or subsequent right to remedy the failure by the Company to observe or comply with any provision hereof. Section 7.06. Notice of Default. The Company shall notify a Responsible Officer of the Trustee immediately and in writing if it becomes aware of the occurrence of any Event of Default hereunder or of any fact, condition or event which, with the giving of notice or passage of time or both, would become an Event of Default.

The Bonds are not and never shall become general obligations of the Authority. (ii) Neither the Authority, the State, nor any of its political subdivisions shall be directly, indirectly, contingently or morally obligated to use any other moneys or assets to pay all or any portion of the debt service due on the Bonds, to levy or to pledge any form of taxation whatever therefor or to make any appropriation for their payment. (iii) The State shall not in any event be liable for the performance of any pledge, obligation or agreement of any kind whatsoever that may be undertaken or made by the Authority or the Obligor.

(iv) The Bonds are not a pledge of the faith and credit of the Authority, the State or any of its political subdivisions nor do they constitute indebtedness within the meaning of any constitutional or statutory debt limitation. Neither the Bonds, this Agreement, nor any of the agreements or obligations of the Authority or the Obligor shall be construed to (i) constitute an indebtedness or obligation, general, moral or otherwise, of the State or the Authority within the meaning of any constitutional or statutory provisions or (ii) give rise 21

to any pecuniary liability on, or be a charge against, the general credit or taxing powers of the State or the Authority.
