Article IV

Loan and Provisions for Payment

Section 4.1. Issuance of Bonds; Loan to Company. In order to provide for the refunding of the outstanding principal amount of the Prior Bonds, the Issuer will issue, sell and deliver the Bonds to the Underwriters and deposit the proceeds of the Bonds with the Trustee as provided in Section 3.1 hereof. Such deposit shall constitute a loan to the Company under this Agreement. The Issuer authorizes the Trustee to disburse the proceeds of the Bonds as provided in Section 3.1 hereof and to make disbursements out of such funds as in said Section 3.1 provided. The Company hereby approves the Indenture and the issuance by the Issuer of the Bonds.

Section 4.2. Repayment of Loan The Company will repay the loan made to it under Section 4.1 as follows: before 11:00 a.m. (local time at the principal corporate trust office of the Trustee) on each day on which any payment of principal of, premium, if any, or interest on the Bonds shall become due (whether at maturity, or upon redemption or acceleration or otherwise), the Company will pay, 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 debt service on the Bonds in full in a timely manner. The First Mortgage Bonds shall be registered in the name of the Trustee. It is intended that payments made with respect to the First Mortgage Bonds shall be made at such time and in such amounts as shall be sufficient to enable the Trustee to make timely payment of principal of, premium, if any, and interest on the Bonds. If such day on which any payment shall become due is not a Business Day, then the payment required by this Section shall be made on or before the succeeding Business Day. If the Company defaults in any payment required by this Section 4.2, the Company will pay interest (to the extent allowed by law) on such amount until paid at the rate provided for in the Bonds. In order to effect the repayment of the loan with payments made on the First Mortgage Bonds, the Company will cause payments of principal, premium (if any) and interest to be made directly to the Trustee without surrender or presentation of such First Mortgage Bonds to the First Mortgage Trustee under the First Mortgage Supplemental Indenture. Such payments shall be made by bank wire transfer of federal or other immediately available funds to the following address or in such other manner or to such other accounts as the Trustee may from time to time direct in writing:

	Bank One, N.A.
	ABA #044000027
	DDA #980222594

	F/B/O: Peoples Gas Light and Coke Company
	Trust Account No: 204854001
	Attention: Xxxxxx Xxxxxxx

Payments, and amounts which are deemed to be payments as hereinafter provided, of principal of, premium, if any, and interest on the First Mortgage Bonds by the Company to the

-13-

Trustee, as assignee of the Issuer, shall constitute payments of such amounts on the loan under this Section 4.2. Principal of, premium, if any, and interest on the Bonds shall be payable from payments made by the Company to the Trustee of principal of, premium, if any, and interest on the First Mortgage Bonds delivered hereunder.

In furtherance of the foregoing, so long as any Bonds are outstanding the Company will pay all amounts required to prevent any deficiency or default in any payment of the Bonds, including any deficiency caused by an act or failure to act by the Trustee, the Company, the Issuer or any other person.

All amounts payable under this Section 4.2 by the Company are assigned by the Issuer to the Trustee pursuant to the Indenture for the benefit of the Bondholders. The Company consents to such assignment.

All First Mortgage Bonds shall equally and ratably secure all outstanding Bonds.

Section 4.3. Satisfaction of Repayment of Loan and Other Amounts Payable. To evidence its obligation to make the loan payments specified in Section 4.2 hereof, and concurrently with the issuance of the Bonds, the Company will deliver its First Mortgage Bonds to the Issuer and the Issuer hereby acknowledges receipt of the First Mortgage Bonds and directs the Company to deliver the First Mortgage Bonds to the Trustee. Each such First Mortgage Bond issued with respect to the Bonds will be in substantially the form set forth in the First Mortgage Supplemental Indenture, and the First Mortgage Bonds will be in substantially the same form with necessary and appropriate variations, omissions and insertions as permitted and required by this Agreement and the First Mortgage Supplemental Indenture, and the First Mortgage Bonds will (i) be initially issued in a principal amount equal to the aggregate principal amount of the Bonds, (ii) provide for payments of interest on the unpaid balance thereof equal to the payments of interest on the Bonds, (iii) contain provisions in respect of the payment of principal, whether at maturity, by redemption or acceleration, corresponding to the payment provisions of the Bonds, (iv) require all payments of principal of or interest on the First Mortgage Bonds to be made on or prior to the due date for the corresponding payment to be made on the Bonds and in the same coin or currency, and (v) otherwise comply with this Section 4.3 and Sections 4.2, 4.7 and 4.8 hereof.

Whenever payment or provision therefor has been made to the Trustee in respect of the principal of or interest on all or any portion of the Bonds in accordance with the Indenture (whether at maturity or upon redemption or acceleration), the First Mortgage Bonds 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 interest on the Bonds. If the Bonds are thereby deemed paid in full, the corresponding First Mortgage Bonds shall be cancelled and returned to the Company. 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 under the First Mortgage Bonds.

-14-

If for any reason amounts paid to the Trustee on the First Mortgage Bonds, together with other moneys held by the Trustee and available for that purpose, would not be sufficient to make the corresponding payments of principal of and interest on the Bonds corresponding to such First Mortgage Bonds when such payments become due, the Company will pay the amounts required from time to time to make up any such deficiency.

The Issuer, by the terms of the Indenture, shall require the Trustee to notify in writing the person or institution then serving as First Mortgage Trustee under the First Mortgage Indenture, of all payments or credits with respect to the First Mortgage Bonds.

Section 4.4. No Defense or Set-Off. The obligations of the Company to make the payments required under Section 4.2 hereof shall be absolute and unconditional without defense, recoupment 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, including, without limitation, any acts or circumstances that may constitute failure of consideration, destruction of or damage to the Project, condemnation, failure of title, or commercial frustration of purpose, or failure of the Issuer to perform and observe any agreement, whether express or implied, or any duty, liability or obligation to the Company, whether or not arising out of or connected with this Agreement, it being the intention of the parties that the payments required under Section 4.2 hereof will be paid in full when due without any delay or diminution whatsoever.

Section 4.5. Assignment of Issuer's Rights. As security for the payment of the Bonds, the Issuer will, concurrently with the issuance of the Bonds, pledge and assign to the Trustee the Issuer's rights under this Agreement (except the right to receive payments, if any, under Sections 5.3. 5.4, 5.8 and 6.4 hereof), including the right of the Issuer to receive the First Mortgage Bonds and the right to receive payments thereunder and hereby covenants and agrees with the Company to pledge, assign and deliver the First Mortgage Bonds issued pursuant to Section 4.3 hereof to the Trustee. The Issuer directs the Company, and the Company agrees to pay to the Trustee at its principal corporate trust office, all payments on the First Mortgage Bonds and other payments due and payable to the Trustee hereunder. The Company will make payments directly to the Trustee without defense or set-off by reason of any dispute between the Company and the Trustee or the Issuer. The Issuer hereby agrees that the Trustee as assignee may enforce any and all rights and remedies hereunder and under the First Mortgage Bonds, but the Issuer retains the right to proceed in its own name against the Company for the enforcement or the specific performance of any obligation of the Company under Sections 5.3, 5.4, 5.8 and 6.4 of this Agreement.

The Issuer and the Company covenant and agree that the First Mortgage Bonds will at all times be (i) in fully registered (both principal and interest) form; (ii) registered in the name of the Trustee; (iii) non-transferable except as provided in the First Mortgage Indenture; and (iv) appropriately marked to indicate clearly the restrictions on the transfer thereof imposed by this Agreement.

-15-

Section 4.6. Payment of Purchase Price. To the extent not otherwise provided for herein, the Company agrees to pay or cause to be paid amounts sufficient to pay the purchase price of any Bond at the time and in the manner payable pursuant to Article IV of the Indenture.

Section 4.7. Prepayments. The Company may at any time prepay to the Trustee all or any part of the amounts payable under Section 4.2 hereof. A prepayment shall not relieve the Company of its obligations under this Agreement until all the Bonds have been paid or provision for the payment of all the Bonds has been made in accordance with the Indenture. Whenever the Bonds are redeemable in whole or in part, the Issuer will redeem the same upon the request of the Company and the Company covenants and agrees to pay an amount equal to the applicable redemption price of such Bonds as a payment due pursuant to this Section 4.7 and as prepayment of principal of, premium, if any, and interest due on the First Mortgage Bonds. Notwithstanding the foregoing, the Bonds may only be redeemed in accordance with the provisions set forth in the Indenture.

Section 4.8. Payments Assigned; Obligations of Company Unconditional. It is understood and agreed that all right, title and interest of the Issuer to this Agreement and the First Mortgage Bonds (except the right to receive payments, if any, under Sections 5.3, 5.4, 5.8 and 6.4 hereof) are assigned to the Trustee as security for the payment of the Bonds. The Company assents to such assignment, and hereby agrees that the obligations of the Company to make the payments required by Sections 4.2, 4.3 and 4.7 hereof and to perform its other agreements contained in this Agreement and under the First Mortgage Bonds shall be absolute and unconditional and the Company (a) will not suspend or discontinue any payments provided for in such Sections and (b) will not terminate this Agreement for any reason. The obligations of the Company to make the payments required under Section 4.2 hereof and under the First Mortgage Bonds shall be absolute and unconditional, without defense, recoupment 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, including, without limitation, any acts or circumstances that may constitute failure of consideration, destruction over damage to the Project, condemnation, failure of title or commercial frustration of purpose, or failure by the Issuer to perform and observe any agreement, whether express or implied, or any duty, liability or obligation to the Company, whether or not arising out of or connected with this Agreement, it being the intention of the parties that the payments required by the First Mortgage Bonds will be paid in full when due without any delay or diminution whatsoever.

The indemnifications set forth herein shall survive the termination of the Indenture and/or the resignation or removal of the Trustee.

Section 5.5. Tax Exempt Status of the Bonds. The Company acknowledges that it has executed, in connection with the issuance of the Bonds, the Project Certificate. The Company understands that the purpose of the Project Certificate is to set forth (i) representations of certain facts regarding the Project and the Company and (ii) covenants regarding the future conduct and activities of the Company, and that the information, representations and covenants set forth in the Project Certificate have been relied upon by Xxxxxxx and Xxxxxx LLP, Bond Counsel for the Bonds, in determining that interest on the Bonds is excludable from gross income for federal income tax purposes. Accordingly, the Company covenants that all information and representations in the Project Certificate are accurate and reasonable to the best of the Company's knowledge and belief and that the Company will comply with all covenants in the Project Certificate as if such covenants were fully set forth herein.

Notwithstanding any other provision hereof, the Company covenants and agrees that it will not knowingly take or authorize or permit, to the extent such action is solely within the control of the Company, any action to be taken with respect to the Project, the proceeds of the Bonds (including investment earnings thereon) or any insurance, condemnation or other proceeds derived directly or indirectly in connection with the Project which will result in the loss of the exclusion of interest on the Bonds from federal gross income under Section 103 of the Code (except for any Bond during any period while such Bond is held by a person referred to in Section 147(a) of the Code); and the Company also will not knowingly omit to take any action in its power which, if omitted, would cause such result. The Company covenants for the benefit of the Bondholders to comply with all of the requirements of Section 507 of the Indenture. The preceding sentence shall control in case of conflict or ambiguity with any other provision of this Agreement.

The Company covenants and agrees to notify the Trustee, the Insurer and the Issuer of the occurrence of any event of which the Company has notice and which event would require the Company to prepay the amounts due hereunder because of a redemption of the Bonds upon a determination of taxability.

-19-

The Company acknowledges that in the event of an examination by the Internal Revenue Service of the exclusion of interest on the Bonds from the gross income of the owners thereof for federal income tax purposes, the Issuer is likely to be treated as the "taxpayer" in such examination, and agrees that it will respond, and will direct the Issuer to respond, in a commercially reasonable manner to any inquiries from the Internal Revenue Service in connection with such an examination. The Issuer covenants that it will cooperate with the Company, at the Company's expense and at its direction, in connection with any such examination.

Section 5.6. Covenants and Representations with Respect to Arbitrage. The Issuer, to the extent it has any control over proceeds of the Bonds and solely in reliance upon the Company, and the Company covenants and represents to each other and to and for the benefit of the owners of the Bonds and the Beneficial Owners that so long as any of the Bonds remain Outstanding, moneys on deposit in any fund in connection with the Bonds, whether such moneys were derived from the proceeds of the sale of the Bonds or from any other sources, will not be used in a manner which will cause the Bonds to be "arbitrage bonds" within the meaning of Section 148 of the Code and any lawful regulations promulgated thereunder, as the same exist on this date or may from time to time hereafter be amended, supplemented or revised. The Issuer, to the extent it has any control over proceeds of Bonds and solely in reliance on the Company, and the Company covenant for the benefit of the owners of the Bonds and the Beneficial Owners to comply with all of the provisions of the Tax Agreement. The Company reserves the right, however, to make any investment of such moneys permitted by State law, if, when and to the extent that said Section 148 or regulations promulgated thereunder shall be repealed or relaxed or shall be held void by final judgment of a court of competent jurisdiction, but only upon receipt of an opinion of Bond Counsel with respect to such investment.

Section 5.7. Redemption of Bonds. If the Company is not in default in the payments under Section 4.2 hereof, the Issuer, upon reasonable assurance from the Company that the Company shall make sufficient funds available, at the request at any time of the Company and if the same are then callable, shall forthwith take all steps that may be necessary under the provisions of the Indenture to effect redemption of all or part of the then outstanding Bonds, as may be specified by the Company, on the redemption date specified by the Company and on which such redemption may be made under such applicable provisions.

Section 5.8. Taxes and Governmental Charges. The Company will promptly pay, as the same become due, all lawful taxes, assessments and governmental charges of any kind whatsoever including, without limitation, any tax equivalent required by the laws of the State of Illinois or income, profits, property and excise taxes levied or assessed by federal, state or any municipal government upon the Issuer with respect to the Project or any part thereof or any payments under this Agreement. The Issuer agrees to give the Company prompt notice of any such assessments or governmental charges.

The Company may, at its expense and in its own name and behalf or in the name and behalf of the Issuer, if it is a necessary party thereto, in good faith contest any such taxes,

-20-

assessments and other charges and, in the event of any contest, permit the taxes, assessments or other charges so contested to remain unpaid during the period of such contest and any appeal therefrom, provided that during such period enforcement of any such contested item shall be effectively stayed. The Issuer, at the expense of the Company, will cooperate fully with the Company in any such contest.

Section 5.9. Financial Reports. The Company agrees to have an annual audit made by its regular independent certified public accountants and, upon request, to furnish the Insurer, the Issuer and the Trustee (within 60 days after receipt of such request by the Company but in no event earlier than 90 days after the end of the Company's fiscal year) with a balance sheet and statements of income, retained earnings and cash flows 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 the opinion of such accountants. The Trustee will hold such reports solely for the purpose of making them available at its principal corporate trust office for examination by the Bondholders, and is not required to notify the Bondholders of the contents of any such report.

The Company will permit the Insurer to discuss the affairs, finances and accounts of the Company or any information the Insurer may reasonably request regarding the security for the Bonds with appropriate officers of the foregoing. Upon receipt of reasonable prior written notice to an appropriate officer of the Company or the Trustee, as applicable, at their respective addresses as set forth in Section 7.6 hereof, the Trustee or the Company, as appropriate, will permit the Insurer to make copies of all books and records relating to the Bonds at any reasonable time.

Section 5.10. Recordation and Other Instruments.

To continue the perfection of the security interest evidenced by such security agreements or financing statements, the Company shall file and record such necessary continuation statements or supplements thereto and other instruments from time to time as may be required pursuant to the provisions of said Uniform Commercial Code or other similar law to fully preserve and protect the security interest of the Trustee in the Trust Estate. The Company, at its own expense, shall file and refile such instruments which shall be necessary to preserve and perfect the lien of the Indenture upon the Trust Estate until the principal of, premium, if any, and interest on the Bonds issued under the Indenture shall have been paid or provision for their payment shall be made as provided in the Indenture. Except to the extent it is exempt therefrom, the Company will pay or cause to be paid all filing, registration and recording fees incident to each such filing, registration and recording, and all expenses incident to the preparation, execution and acknowledgment of such instruments of further assurance, and all

-21-

Federal or State fees and other similar fees, duties, imposts, assessments and charges arising out of or in connection with the execution and delivery of this Agreement, the Indenture and such instruments of further assurance.

The Issuer shall have no responsibility for the preparation, filing or recording of any instrument, document or financing statement or for the maintenance of any security interest intended to be perfected thereby. The Issuer will execute such instruments as may be necessary in connection with such filing or recording.

Section 5.11. Compliance with Laws. The Company shall, through the term of this Agreement and at no expense to the Issuer, comply or cause compliance with all laws, ordinances, orders, rules and regulations of duly constituted public authorities which may be applicable to the Project or to the repair and alteration thereof, or to the use or manner of use of the Project, except to the extent that a failure to so comply will not materially adversely affect the Project or the Company's ability to perform its obligations under this Agreement, the Indenture or the First Mortgage Supplemental Indenture. In the event of any failure to comply with the foregoing covenant, the Company will promptly notify the Issuer and take all necessary action to remedy or cure such failure.

Section 5.12. Continuing Disclosure. The Company hereby covenants and agrees, whenever a Term Rate Period is in effect or if otherwise required by Rule 15c2-12, to comply with the continuing disclosure requirements for the Bonds as promulgated under Rule 15c2-12, as it may from time to time hereafter be amended or supplemented. Notwithstanding any other provision of this Agreement, failure by the Company to comply with the requirements of Rule 15c2-12 applicable to the Bonds, as it may from time to time hereafter be amended or supplemented, shall not be considered an Event of Default hereunder or under the Indenture; however, the Trustee may (and at the written request of the owners of not less than 25% in aggregate principal amount of the Bonds then outstanding and upon receipt of indemnity satisfactory to the Trustee, shall), or any Bondholder or "Beneficial Owner" of any Bonds may take such actions as may be necessary and appropriate, including seeking mandate or specific performance by court order, to cause the Company to comply with its obligations pursuant to this Section 5.12. For purposes of this Section 5.12, "Beneficial Owner" means any person who has or shares the power, directly or indirectly, to make investment decisions concerning ownership of any Bonds (including persons holding Bonds through nominees, depositories or other intermediaries).

Section 5.13. No Recourse to Issuer. The obligations of the Issuer under the Indenture and the Bonds are special, limited obligations of the Issuer, payable solely out of the revenues and income derived under this Agreement and as otherwise provided under this Agreement and the Indenture. The Bonds shall not be deemed to constitute an indebtedness or an obligation of the Issuer, the State or any political subdivision thereof, within the purview of any constitutional limitation or statutory provision, or a charge against the general credit or taxing powers, if any, of any of them. The Issuer has no taxing power. Neither the Issuer nor any member, director, officer, employee or agent of the Issuer nor any person executing the Bonds shall be liable personally for the Bonds or be subject to any personal liability or

-22-

accountability by reason of the issuance of the Bonds. No recourse shall be had for the payment of the principal of, premium, if any, and interest on any of the Bonds or for any claim based thereon or upon any obligation, covenant or agreement contained in the Indenture or this Agreement against any past, present or future member, officer, agent or employee of the Issuer, or any incorporator, member, officer, employee, director or trustee of any successor corporation, as such, either directly or through the Issuer or any successor corporation, under any rule of law or equity, statute or constitution or by the enforcement of any assessment or penalty or otherwise, and all such liability of any such incorporator, member, officer, employee, director, agent or trustee as such is hereby expressly waived and released as a condition of and consideration for the execution of the Indenture or this Agreement and the issuance of the Bonds.

Section 5.14. No Warranty by Issuer. The Company recognizes that the Issuer has not made an inspection of the Project or of any fixture or other item constituting a portion thereof, and the Issuer makes no warranty or representation, express or implied or otherwise, with respect to the same or the location, use, description, design, merchantability, fitness for use for any particular purpose, condition or durability thereof, or as to the Issuer's or the Company's title thereto or ownership thereof or otherwise, it being agreed that all risks incident thereto are to be borne by the Company. In the event of any defect or deficiency of any nature in the Project or any fixture or other item constituting a portion thereof, whether patent or latent, the Issuer shall have no responsibility or liability with respect thereto. The provisions of this Section 5.14 have been negotiated and are intended to be a complete exclusion and negation of any warranties or representations by the Issuer, express or implied, with respect to the Project or any fixture or other item constituting a portion thereof, whether arising pursuant to the Uniform Commercial Code of the State of Illinois or another law.

Section 5.15. Annual Certificate. The Company will furnish to the Issuer, the Insurer and to the Trustee on or before January 31 of each year, a certificate of the Company signed by the Authorized Company Representative stating that the Company has made a review of its activities during the preceding calendar year for the purpose of determining whether or not the Company has complied with all of the terms, provisions and conditions of this Agreement and the Company has kept, observed, performed and fulfilled each and every covenant, provision and condition of this Agreement on its part to be performed and is not in default in the performance or observance of any of the terms, covenants, provisions or conditions hereof, or if the Company shall be in default such certificate shall specify all such defaults and the nature thereof.

Section 5.16. Indenture Provisions. The Indenture provisions concerning the Bonds and the other matters therein are an integral part of the terms and conditions of the loan made by the Issuer to the Company pursuant to this Agreement and the execution of this Agreement shall constitute conclusive evidence of approval of the Indenture by the Company to the extent it relates to the Company. Additionally, the Company agrees that, whenever the

-23-

Indenture by its terms imposes a duty or obligation upon the Company, such duty or obligation shall be binding upon the Company to the same extent as if the Company were an express party to the Indenture, and the Company hereby agrees to carry out and perform all of its obligations under the Indenture as fully as if the Company were a party to the Indenture.

The Trustee, as the assignee of the Issuer and as an owner of the First Mortgage Bonds, shall have the remedies provided in the First Mortgage Indenture for owners of bonds issued thereunder upon the happening of any "event of default" as defined in the First Mortgage Indenture.

The foregoing provisions of Section 6.1(c) are subject to the following limitations: if by reason of force majeure the Company is unable in whole or in part to carry out its agreements on its part herein contained other than the obligations on the part of the Company contained in Sections 4.2, 4.3, 5.3, 5.4, 5.7 and 6.4 hereof the Company shall not be deemed in default during the continuance of such inability. The term "force majeure" as used herein shall mean, without limitation, the following: acts of God; strikes, lockouts or other industrial disturbances; acts of public enemies; orders of any kind of the government of the United States or of the State of Illinois or any of their departments, agencies, or officials, or any civil or military authority; insurrections; riots; epidemics; landslides; lightning; earthquakes; volcanic eruptions; fires; tornadoes; storms; floods; washouts; droughts; arrests; restraint of government and people; civil disturbances; explosions; breakage or accidents to machinery, transmission lines, pipes or canals; partial or entire failure of utilities; failure of suppliers; or any other cause or event not reasonably within the control of the Company. The Company agrees, however, to remedy with all reasonable dispatch 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

-25-

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 judgment of the Company unfavorable to the Company.

Section 6.2. Remedies on Default. Upon the occurrence of an event of default described in Section 6.1(a) or Section 6.1(b) hereof, the Trustee, as the Issuer's assignee and as holder of the First Mortgage Bonds, shall have the remedies provided in the First Mortgage Indenture for holders of bonds issued thereunder as set forth in Article X thereof. Any waiver of an event of default under the First Mortgage Indenture which constitutes an event of default under Section 6.1(a) or Section 6.1(b) hereof shall constitute a waiver of an event of default under this Agreement.

Upon the occurrence and continuance of an event of default referred to in Section 6.1 hereof, the Trustee, as assignee of the Issuer, may also take any one or more of the following remedial steps:

(a) by mandamus, or other suit, action or proceeding at law or in equity, enforce all rights of the Issuer, and require the Company to carry out any agreements with or for the benefit of the owners of the Bonds and to perform its duties under this Agreement and the First Mortgage Bonds; and

(b) by action or suit in equity enjoin any acts or things which may be unlawful or in violation of the rights of the Issuer.

Any amounts collected pursuant to action taken under this Section 6.2 shall be paid into the Bond Fund and applied in accordance with the provisions of the Indenture or, if the Bonds have been fully paid (or provision for payment thereof has been made in accordance with the provisions of the Indenture), to the Company.

Section 6.3. No Remedy Exclusive. No remedy herein conferred upon or reserved to the Issuer or the Trustee (as assignee of the Issuer) 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 (as assignee of the Issuer) 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.

Section 6.4. Agreement to Pay Attorneys' Fees and Expenses. In the event the Company should default under any of the provisions of this Agreement and the Issuer or the Trustee should employ attorneys 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 demand therefor

-26-

pay to the Trustee, the Issuer or, if so directed by the Issuer, to the attorneys for the Issuer the reasonable fees of such attorneys 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. Notwithstanding the foregoing, if, after the acceleration of the maturity of the outstanding Bonds by the Trustee pursuant to Section 902 of the Indenture, all arrears of interest on the outstanding Bonds and interest on overdue installments of interest (to the extent permitted by law) at a rate per annum which is equal to the rate per annum borne by the Bonds in respect of which such default shall have occurred and the principal of and 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, all other things shall have been performed in respect of which there was a default, 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 such event of default under the Indenture shall be waived by the Trustee with the consequence that under Section 902 of the Indenture such acceleration is rescinded, then the Company's default hereunder shall be deemed to have been waived by the Trustee (as assignee of the Issuer) and no further action in accordance with the Indenture or consent by the Trustee or the Issuer shall be required.

Section 6.6. Rights of the Insurer. All rights and remedies given in this Article to the Bondowners to pursue legal remedies shall also extend to the Insurer unless an Insurer Default (as defined in the Indenture) has occurred and is continuing.

Section 7.12. Default by the Issuer - Limited Liability.

The Issuer does not assume general liability for the repayment of the Bonds or for the costs, fees, penalties, taxes, interest, commissions, charges, insurance or any other payments recited herein, and shall be obligated to pay the same only out of the amounts payable by the Company hereunder.

(a) On any day which the Bonds bear interest in a Daily Rate Mode, a Weekly Rate Mode, a Quarterly Rate Mode, a Semiannual Rate Mode, a Flexible Rate Mode or at a Term Rate for a Term Rate Period (other than a Term Rate Period which extends to the Maturity Date), the Company shall, unless otherwise consented to in writing by the Insurer (which such consent shall be at the

-29-

absolute and sole discretion of the Insurer), provide for the delivery to the Trustee of a Liquidity Facility to provide liquidity support for the Bonds. Any Liquidity Facility (i) must be acceptable to the Insurer and (ii) must be sufficient to cover the full amount of the purchase price of the Bonds on any tender thereof (with the amount of interest so covered to be determined by the rating agencies then rating the Bonds). Any Liquidity Facility shall be payable to the Trustee for the benefit of the owners of the Bonds and shall have administrative provisions reasonably satisfactory to the Trustee. Simultaneously with the delivery of such Liquidity Facility to the Trustee, the Company shall provide the Trustee with (i) an opinion of Bond Counsel to the effect that the delivery of such Liquidity Facility is authorized under the Indenture, complies with the terms of the Indenture and will not have an adverse effect on the exclusion of the interest on the Bonds from gross income for purposes of federal income taxation and (ii) such other matters or showings as shall be required by the rating agencies then rating the Bonds. The Company hereby covenants and agrees to give the Issuer, the Trustee, the Remarketing Agent and the Insurer written notice of intention to deliver any such Liquidity Facility at least fifteen (15) Business Days prior to the date on which the Company expects to deliver such Liquidity Facility.

(b) If the credit rating assigned to the financial strength of the Insurer is withdrawn, suspended or reduced below the two highest financial strength Rating Categories (without regard to subcategories) by any of Fitch, Xxxxx'x or S&P, the Company may, at its option, obtain an additional financial guaranty insurance policy to further secure the payment of the principal of an interest on the Bonds when due. The Company shall not direct the Trustee to surrender, cancel, terminate, or amend or modify in any material respect the Insurance Policy, or substitute such additional financial guaranty insurance policy for the Insurance Policy. The Trustee shall give notice of the receipt of such additional financial guaranty insurance policy to each rating agency then rating the Bonds and the owners of the Bonds. Simultaneously with the delivery of such additional financial guaranty insurance policy to the Trustee, the Company shall provide the Trustee with (i) an opinion of Bond Counsel to the effect that the delivery of such additional financial guaranty insurance policy is authorized under the Indenture, complies with the terms of the Indenture and will not have an adverse affect on the exclusion of the interest on the Bonds from gross income for purposes of federal income taxation and (ii) such other matters or showings as shall be required by the rating agencies then rating the Bonds.
