To the extent such withdrawal of cash is based upon Unbonded Bondable Property as permitted by Section 11.01(a)(ii) , the Company shall comply with all applicable provisions of Article III as if such Unbonded Bondable Property were made a basis for the authentication and delivery of Bonds thereon equivalent in principal amount to the amount of the cash to be withdrawn on such basis. To the extent such withdrawal of cash is based upon the right to the authentication and delivery of Bonds pursuant to Section 11.01(a)(iii) , the Company shall comply with all applicable provisions of Article IV relating to such authentication and delivery as if new Bonds were being authenticated and delivered in principal amount equal to the amount of cash being withdrawn; recognizing that, in each such case, the action being taken is the withdrawal of cash rather than the authentication and delivery of Bonds.

(c) Any withdrawal of cash pursuant to Section 11.01(a)(ii) or Section 11.01(a)(iii) shall operate as a waiver by the Company of its right to the authentication and delivery of Bonds on the basis of which such cash was withdrawn, and such Bonds may not thereafter be authenticated and delivered hereunder on such basis, and the amount of any Bondable Property, Bonds or Prior Lien Debt which have been made the basis for such withdrawal shall be Bonded.

(d) The Trustee shall use reasonable efforts to collect the principal of and interest on any Governmental Obligations and purchase money obligations secured by a purchase money mortgage held by the Trustee as and when such principal and interest become payable. Unless the Company is in default in the payment of any principal of or interest on any Outstanding Bond or any Default shall be continuing, the interest on any such obligation received by the Trustee shall be paid over to the Company, and any payments received by the Trustee on account of the principal of any such obligation in excess (as evidenced by an Officers’ Certificate) of the amount of credit used by the Company in respect of such obligation upon the release of any Mortgaged Property from the Lien of the Mortgage shall also be paid to the Company.

(e) The Trustee shall have and may exercise all the rights and powers of an owner of obligations secured by purchase money mortgage held by the Trustee and of all substitutions therefor and, without limiting the generality of the foregoing, may collect and receive all insurance moneys payable to it under any provision thereof and apply the same in accordance with the provisions thereof, may consent to extensions thereof at a higher or lower rate of interest, may join in any plan or plans of voluntary or involuntary reorganization or readjustment

48

or rearrangement and may accept and hold under this Indenture new obligations, stocks or other securities issued in exchange therefor under any such plan, and any discretionary action which the Trustee may be entitled to take in connection with any such obligations or substitutions therefor shall be taken, so long as no Default has occurred and is continuing, in accordance with the written request of the Company, evidenced by an Officers’ Certificate, or, while a Default is continuing, in the discretion of the Trustee, provided that the Trustee shall have no obligation to exercise any such discretion unless it receives instructions satisfactory to it from the holders of not less than a majority in aggregate principal amount of the Outstanding Bonds pursuant to Section 12.15(d) .

Section 11.02 . Moneys to be held in trust; investment thereof . (a) Subject to Section 18.02 , all cash received by the Trustee shall, until withdrawn, used, invested or applied as provided in this Indenture, be held in trust uninvested, for the purposes for which such cash was received, but need not be segregated from other funds except as directed by the Company or as and to the extent required by law.

(b) After compliance with any applicable legal requirements, the Trustee may deposit all or any part of cash received by it as Trustee in certificates of deposit or demand accounts, to its credit as Trustee in its own banking department or, with the consent of the Company, in any bank or trust company having a combined capital and surplus of not less than Fifty Million Dollars ($50,000,000), evidenced in the manner described in Section 14.01 ; so long as no Default is continuing, the Trustee shall pay to the Company any interest earned on any such certificate or account.

(c) When so directed by an Officers’ Certificate, the Trustee shall invest all or any part of such cash received by it in any Investment Securities; and the Trustee, when so directed by an Officers’ Certificate, shall sell or repurchase all or any part of such Investment Securities. Such Investment Securities shall be held in trust for the account of the Bondholders by the Trustee (or, in the case of moneys delivered pursuant to Section 9.03 , held in trust for the account of the holders of the Bonds to be redeemed); provided , however , that the proceeds of such Investment Securities representing interest shall be paid or credited to the Company and shall not constitute Mortgaged Property. If any such sale or any payment on the maturity of any such Investment Securities held by the Trustee, shall produce a net sum less than the cost (including accrued interest and investment expenses) of such Investment Securities sold or paid, the Company will promptly pay to the Trustee such amount of cash as will, with the net proceeds of such sale or such payment, equal the cost (including accrued interest and investment expenses) of such Investment Securities so sold or paid; and if any such sale or any payment at the maturity of any such Investment Securities held by the Trustee, shall produce a net sum greater than the cost (including accrued interest and investment expenses) of such Investment Securities so sold or paid the Trustee shall, if no Default is continuing, pay to the Company the amount of such excess. The Company will also pay to the Trustee all brokers’ fees and other expenses reasonably incurred by the Trustee in connection with its investment of such cash and the sale of such Investment Securities.

(d) The Trustee shall allow interest on any cash held by it under this Indenture and deposited by it in its banking department, at the current rate or rates, if any, from time to time paid by it on similar deposits of like size and nature over like periods of time, unless in a

49

particular instance the Trustee and the Company shall otherwise agree. Interest so allowed and interest received by the Trustee from deposits in other banks and trust companies of cash which is a part of the Mortgaged Property made pursuant to Section 11.02(b) , except as otherwise herein provided in respect of particular cash, shall, if no Default is continuing, be paid or credited to the Company by the Trustee.

(e) When so directed by an Officers’ Certificate, the Trustee shall establish one or more accounts for the deposit and/or investment of monies received by it, including a separate account from which all cash payable by the Trustee on behalf of the Company shall be paid and into which cash shall be deposited by the Company, or by the Trustee on behalf of the Company from other accounts or investments held or managed by the Trustee, as needed, so that such account shall be operated with a zero balance.

51

this Indenture, the Mortgage or the Collateral Trust Agreement (as applicable) or in aid of the execution of any power granted by this Indenture, the Mortgage or the Collateral Trust Agreement or for the foreclosure of the Mortgage, or for the enforcement of any other appropriate legal or equitable remedy, as the Trustee, being advised by counsel, may deem most effectual to protect and enforce any of its rights or exercise of any of its duties hereunder; provided, that the Trustee shall have no obligation to exercise any such discretion unless it receives instructions satisfactory to it from the holders of not less than a majority in aggregate principal amount of the Outstanding Bonds pursuant to Section 12.15(d).

This provision, however, is subject to the condition that if at any time after the principal of such Bonds shall have been so declared due and payable and before any sale of the Mortgaged Property shall have been made pursuant to the Collateral Trust Agreement, all arrears of interest upon all of such Bonds, with interest upon overdue installments of interest at the same rates respectively as were borne by the respective Bonds on which installments of interest were overdue, shall either be paid by or on behalf of the Company or be collected out of the Mortgaged Property, and all Defaults shall have been remedied, then the holders of not less than a majority in aggregate principal amount of the Outstanding Bonds, by written notice to the Company and to the Trustee, may rescind such declaration and its consequences and in such event the Trustee shall promptly direct the Collateral Trustee to discontinue its proceedings to enforce its rights under the Mortgage by foreclosure or otherwise; but no such rescission shall extend to or affect any subsequent Default, or impair any right consequent thereon.

54

by instituting such action, suit or proceeding in its own name; such notification, request and offer of indemnity are hereby declared, in every such case, at the option of the Trustee, to be conditions precedent to the execution by the Trustee of its powers and trusts under this Indenture and to any action or cause of action the Trustee may take or possess for foreclosure of the Mortgage or for the appointment of a receiver or any other remedy hereunder; it being understood and intended that no one or more holders of Outstanding Bonds shall have any right in any manner whatever to affect, disturb or prejudice the Lien of the Mortgage by action of such one or more holders, or to enforce any right under this Indenture, except in the manner herein provided, and that all proceedings at law or in equity shall be instituted, had and maintained in the manner herein provided and for the ratable benefit of all holders of such Outstanding Bonds.

(b) The Trustee shall be entitled to recover judgment as described in Section 12.17(a) , either before, after or during the pendency of any proceedings for the enforcement of the Lien of the Mortgage by the Collateral Trustee, and the right of the Trustee to recover such judgment shall not be affected by any entry upon or sale of Mortgaged Property by the Collateral Trustee, or by the exercise by the Trustee or the Collateral Trustee of any right, power or remedy for the enforcement of this Indenture or the Mortgage; and in case of a sale of Mortgaged Property, and of the application of the proceeds of such sale to the payment of the obligations secured by the Lien of the Mortgage, the Trustee, in its own name and as trustee of an express trust, shall be entitled to enforce payment of and to receive all amounts then remaining due and unpaid upon any and all of the Outstanding Bonds for the benefit of the Bondholders, and shall be entitled to recover judgment for any portion of such obligations remaining unpaid, with interest. No recovery of any such judgment by the Trustee or the Collateral Trustee, and no levy of execution of any such judgment upon any of the Mortgaged Property, or any other property, shall in any manner or to any extent affect the rights of the Trustee, the Bondholders and the Collateral Trustee in respect of the Lien of the Mortgage upon any Mortgaged Property, or any rights, powers or remedies of the Trustee or the Collateral Trustee, or any lien, rights, powers or remedies of the Bondholders, but such lien, rights, powers and remedies of the Trustee and the Collateral Trustee and of the Bondholders shall continue unimpaired as before.

(c) Any moneys received by the Trustee under this Section 12.17 shall be applied by the Trustee to the payment of the amounts then due and unpaid on the Outstanding Bonds in respect of which such moneys shall have been received, ratably and without any preference or

56

priority of any kind, according to the amounts due and payable on such Bonds, respectively, at the date fixed by the Trustee for the distribution of such moneys, upon presentation of the several Bonds and stamping the amount of such payment thereon, if partly paid, and upon surrender thereof, if fully paid.

Section 12.21 . Right of Bondholders to receive payment .

For the purposes of this Section 12.23 , Bonds shall be deemed to be materially adversely affected by such waiver

57

if such waiver materially adversely affects or materially diminishes the rights of holders of such Bonds against the Company or against the Mortgaged Property. The Trustee may in reliance on an Opinion of Counsel determine whether or not, in accordance with the foregoing, Bonds of any particular series would be materially adversely affected by any such waiver and any such determination shall be conclusive upon the holders of Bonds of such series and all other series. Subject to Section 14.01 and Section 14.02 , the Trustee shall not be liable for any such determination made in good faith.

Section 12.23 . Waiver of Usury, Stay or Extension Laws .

Nothing in this Indenture shall prevent any consolidation or merger of the Company with or into, or any conveyance, transfer or lease, subject to the Lien of the Mortgage, of all or substantially all of the Mortgaged Property to, any Person lawfully entitled to acquire, lease or operate the Mortgaged Property; provided , however , and the Company covenants and agrees, that such consolidation, merger, conveyance, transfer or lease shall be upon terms which would fully preserve, and in no respect create any Prior Lien (other than Permissible Encumbrances) on, the Mortgaged Property, or impair the Lien or security of the Mortgage, or any of the rights or powers of the Trustee or the Bondholders under this Indenture or the Collateral Trustee under the Mortgage or the Collateral Trust Agreement; and provided further , that no such consolidation, merger, conveyance, transfer or lease shall be entered into or made by the Company with or to another Person which has outstanding, or which proposes to issue in connection with any such consolidation, merger, conveyance, transfer or lease, any obligations secured by a mortgage, pledge or other lien if as a result of such consolidation, merger, conveyance or lease any of the Mortgaged Property owned by the Company immediately prior thereto would be subjected to the lien of such mortgage, pledge or other lien, unless simultaneously therewith or prior thereto effective provision shall be made to establish the Lien of the Mortgage as superior to the lien of such mortgage, pledge, or other lien with respect to any of the Mortgaged Property then or thereafter acquired by the Company or such other Person, or covenanted to be subject to the Lien of the Mortgage; and provided further , that any such lease shall be made expressly subject to immediate termination by the Company or by the Trustee at any time during the continuance of a Default, and also by the purchaser of the Mortgaged Property so leased at any sale thereof under this Indenture, whether such sale is made under the power of sale conferred in this Indenture or judicial proceedings; and provided further , that, upon any such consolidation, merger, conveyance or

(i) shall enter into a Supplemental Mortgage confirming the prior Lien of the Mortgage upon the Mortgaged Property and extending the Lien of the Mortgage as a first lien, or as a lien subject only to liens affecting the property of the Company prior to such consolidation, merger, conveyance, transfer or lease, to (A) all property which such successor shall thereafter acquire or construct which shall form an integral part of, or be essential to the use or operation of, any property then or thereafter subject to the Lien of the Mortgage, and (B) all renewals, replacements and additional property as may be purchased, constructed or otherwise acquired by such successor from and after the date of such consolidation, merger, conveyance, transfer or lease, as the case may be; and

(ii) any property or franchises which may be purchased, constructed or otherwise acquired by any such successor after the date of any such consolidation, merger, conveyance, transfer or lease; excepting only the property referred to in Section 13.02(b)(i) which shall be and become subject to the Lien of the Mortgage, notwithstanding any such consolidation, merger, conveyance, transfer or lease.

59

Section 13.03 . Right of successor . In case the Company, as permitted by Section 13.01 , shall be consolidated with or merged into any other Person or shall convey or transfer, subject to the Lien of the Mortgage, all or substantially all the Mortgaged Property, the successor formed by such consolidation, or into which the Company shall have been merged, or which shall have received a conveyance or transfer as aforesaid, and upon executing with the Trustee the Supplemental Indenture and Supplemental Mortgage provided for in Section 13.01 and causing such Supplemental Mortgage to be recorded, shall succeed to and be substituted for the Company with the same effect as if such Person had been named herein, and shall have and may exercise under this Indenture the same powers and rights as the Company, and, without in any way limiting or impairing by the enumeration of the following rights and powers the scope and intent of the foregoing, such Person thereafter may cause to be executed, authenticated and delivered, either it its own name or in the name of the Company, such Bonds as might have been executed, issued and delivered by the Company after the date of such consolidation, merger, conveyance or transfer, and had such consolidation, merger, conveyance or transfer not occurred, and upon the order of such Person in lieu of the Company, but subject to all the terms, conditions and restrictions prescribed in this Indenture concerning the authentication and delivery of Bonds, the Trustee shall authenticate and deliver any Bonds delivered to it for authentication which shall have been previously executed by the proper officers of the Company, and such Bonds as such Person shall thereafter, in accordance with this Indenture, cause to be executed and delivered to the Trustee for such purpose, and such Person shall also have and may exercise, subject to all applicable terms, conditions and restrictions prescribed in this Indenture, the rights and powers of the Company as to withdrawal of cash and release of Mortgaged Property from the Lien of the Mortgage, which the Company might have exercised after the date of such consolidation, merger, conveyance or transfer, and had such consolidation, merger, conveyance or transfer not occurred. All of the Bonds so issued or delivered shall in all respects have the same legal right and security as the Bonds theretofore issued or delivered in accordance with the terms of this Indenture as though all of such Bonds had been authenticated and delivered at the date of the execution of this Indenture. As a condition precedent to the execution by such Person and the authentication and delivery by the Trustee of any such Bonds, the withdrawal of cash or the release of Mortgaged Property from the Lien of the Mortgage, under any provision of this Indenture on the basis of Bondable Property acquired, made or constructed by such Person, the Supplemental Mortgage provided for in Section 13.01 , or a subsequent Supplemental Mortgage, shall contain a conveyance or transfer and mortgage in terms sufficient to subject such property to the Lien of the Mortgage; and provided further that the lien created thereby and the lien thereon shall have the same force, effect and standing as the Lien of the Mortgage would have if the Company was not consolidated with or merged into such other Person or did not convey or transfer, subject to the Lien of the Mortgage, all or substantially all the Mortgaged Property, as aforesaid, to such Person, and would itself on or after the date of such consolidation, merger,

60

conveyance or transfer, acquire or construct such property, and in respect thereof request the authentication and delivery of Bonds or the withdrawal of cash or the release of Mortgaged Property from the Lien of the Mortgage as provided in this Indenture.

Section 13.04 . Transfer of less than substantially all . Without limiting the generality of Section 13.01, if following a conveyance, transfer or lease by the Company of any part of the Mortgaged Property the Fair Value of the Mortgaged Property retained by the Company exceeds an amount equal to 10/7 (ten sevenths) of the sum of (x) the aggregate principal amount of Outstanding Bonds plus (y) the aggregate principal amount of outstanding Equal and Ratable Notes plus (z) the aggregate principal amount of outstanding Prior Lien Debt, then the part of the Mortgaged Property so conveyed, transferred or leased shall, in any event, be deemed not to constitute all or substantially all of the Mortgaged Property. Such Fair Value may be established by the delivery to the Trustee of an Independent Engineer’s Certificate stating the Independent Engineer’s opinion of such Fair Value as of a date not more than ninety (90) days before or after such conveyance, transfer or lease. This Article XIII is not intended to limit the Company’s conveyances, transfers or leases of less than all or substantially all of the Mortgaged Property.

Section 14.16 . Acceptance by successor trustee; requirements of predecessor Trustee upon retiring . Any successor trustee appointed hereunder shall execute, acknowledge and deliver to the predecessor trustee, and also to the Company, an instrument accepting such appointment hereunder, and thereupon such successor trustee, without any further act, deed or conveyance, shall become fully vested with all the estates, properties, rights, powers, trusts, duties and obligations of its predecessor in trust hereunder, with like effect as if originally named as trustee herein; but the trustee ceasing to act shall nevertheless, on the written request of the Company, or of the successor trustee, or of the holders of not less than 10% in aggregate principal amount of the then Outstanding Bonds, execute, acknowledge and deliver such instruments of conveyance and further assurance and do such other things as may reasonably be required for more fully and certainly vesting and confirming in such successor trustee all the right, title and interest of the trustee to which such trustee succeeds in such rights, powers, trusts, duties and obligations, and the trustee ceasing to act shall also, upon like request, pay over, assign and deliver to the successor trustee any money or any pledged securities which may then be in the possession of such trustee. If any deed, conveyance or instrument in writing from the Company is required by the new trustee for more fully and certainly vesting in and confirming to such new trustee such estates, properties, rights, powers, trusts, duties and obligations, any and all such deeds, conveyances and instruments in writing shall, on request, be executed, acknowledged and delivered by the Company.

ARTICLE II

Defaults and Remedies

SECTION 2.01. Events of Default. Any Event of Default under the Collateral Trust Agreement (as such term is defined therein) shall constitute an event of default (an “ Event of Default ”) under this Mortgage.

SECTION 2.02. Rights to Take Possession, Operate and Apply Revenues. (a) If an Event of Default shall occur and be continuing, after the expiration of any notice and cure periods as set forth in the Mortgage Bond Indenture, the Mortgagor shall, within ten (10) days of demand of the Mortgagee, forthwith surrender to the Mortgagee actual possession of the Mortgaged Property and, if and to the extent not prohibited by applicable law, the Mortgagee may itself, or by such officers or agents as it may appoint, enter and take exclusive possession of all the Mortgaged Property and of all books, records and accounts relating thereto or located thereon without the appointment of a receiver or an application therefor and exclude the Mortgagor and its agents and employees wholly therefrom.

(b) If the Mortgagor shall for any reason fail to surrender or deliver the Mortgaged Property or any part thereof in accordance with the terms hereof, the Mortgagee may invoke any legal remedies to dispossess the Mortgagor. The Mortgagor will pay to the Mortgagee, upon demand, all reasonable documented and out of pocket expenses of obtaining such judgment or decree, including compensation to the Mortgagee’s attorneys (excluding internal counsel) and agents; and all such expenses and compensation shall, until paid, be secured by this Mortgage.

(c) In each and every Event of Default, and during the continuance thereof, the Mortgagee directly or by its agents or attorney may, to the extent permitted by law, enter upon the Mortgaged Property; may exclude the Mortgagor and its agents and employees wholly therefrom; either directly or by its receivers, agents, employees or attorneys, may use, operate, lease, manage and control the Mortgaged Property, and conduct the business of the Mortgaged Property in any reasonable manner; may make all repairs, renewals, replacements and useful alterations, additions, betterments and improvements to the Mortgaged Property as the Mortgagee may deem necessary and proper; may manage and operate the Mortgaged Property and exercise all rights and powers of the Mortgagor in respect thereof, and be entitled to collect and receive all tolls, earnings, income, rents, issues and profits thereof; and, after deducting all expenses incurred hereunder and all payments which may be made for taxes, assessments, insurance and prior or other proper charges upon the Mortgaged Property or any part thereof, as well as compensation for the services of the Mortgagee, its agents, employees, attorneys (excluding internal counsel) and receivers, the Mortgagee shall apply the moneys it obtains from the foregoing in accordance with the Collateral Trust Agreement.

(d) If at any time after the principal of the Mortgage Bonds, 2002 Indenture Notes and 2006 Indenture Notes shall have been so declared due and payable and before any sale of the Mortgaged Property shall have been made pursuant to this Section 2.02, all arrears of interest upon all of such Mortgage Bonds, 2002 Indenture Notes and 2006 Indenture Notes, with interest upon overdue installments of interest at the same rates respectively as were borne by the respective Mortgage Bonds, 2002 Indenture Notes and 2006 Indenture Notes on which

10

installments of interest were overdue, shall either be paid by the Mortgagor or be collected out of the Mortgaged Property, and all Events of Default shall have been remedied, then the Mortgage Bond Trustee, by written notice to the Mortgagor and to the Mortgagee, may rescind such declaration and its consequences; but no such rescission shall extend to or affect any subsequent Event of Default, or impair any right consequent thereon.

SECTION 2.03. Right to Cure the Mortgagor’s Failure to Perform. Should the Mortgagor fail in the payment, performance or observance of any term, covenant or condition required by this Mortgage or the Mortgage Bond Indenture (but only with respect to the Mortgaged Property), after the expiration of any applicable cure period set forth herein or the Mortgage Bond Indenture, the Mortgagee may pay, perform or observe the same, and all payments made or costs or expenses incurred by the Mortgagee in connection therewith shall be secured hereby and shall be, without demand, immediately repaid by the Mortgagor to the Mortgagee with interest thereon. The Mortgagee is hereby empowered to enter and to authorize others to enter upon the Mortgaged Property or any part thereof for the purpose of performing or observing any such defaulted term, covenant or condition without having any obligation to so perform or observe and without thereby becoming liable to the Mortgagor, to any person in possession holding under the Mortgagor or to any other person, other than as determined to have been caused by the Mortgagee’s own gross negligence or willful misconduct. In connection with any such entry, the Mortgagee shall provide prior written notice, enter during regular business hours (except in the case of an emergency) and use commercially reasonable efforts not to interrupt the Mortgagor’s operations at the Mortgaged Property.

SECTION 2.04. Right to a Receiver. During the continuance of an Event of Default, upon application to a court of competent jurisdiction or as otherwise required by applicable law and without notice, a receiver may be appointed to take possession of, and to operate, maintain and manage, the whole or any part of the Mortgaged Property, and the Mortgagor shall transfer and deliver to such receiver all such Mortgaged Property, wheresoever it may be situated; and in every case, when a receiver of the whole or of any part of such Mortgaged Property shall be appointed under this Section 2.04, or otherwise, the net income and profits of such Mortgaged Property shall be paid over to, and shall be received by, the Mortgagee. Any receiver so appointed shall have all of the rights and powers permitted under the laws of the state wherein the Mortgaged Property is located, including the full power to rent, maintain and otherwise operate the Mortgaged Property upon such terms as may be approved by the court. The Mortgagor shall pay to the Mortgagee upon demand all reasonable documented and out of pocket expenses, including receiver’s fees, reasonable attorney’s fees (excluding internal counsel) and disbursements, costs and agent’s compensation incurred pursuant to the provisions of this Section 2.04; and all such expenses shall be secured by this Mortgage and shall be, without demand, immediately repaid by the Mortgagor to the Mortgagee.

SECTION 2.05. Foreclosure and Sale. (a) If an Event of Default shall occur and be continuing, after the expiration of any notice and cure periods set forth herein or the Mortgage Bond Indenture, the Mortgagee may elect to institute proceedings for the complete foreclosure of this Mortgage, either by judicial action or by power of sale, in which case the Mortgaged Property may be sold for cash or credit in one or more parcels. With respect to any notices required or permitted under the UCC, the Mortgagor agrees that ten (10) days’ prior written notice shall be deemed commercially reasonable. At any such sale by virtue of any judicial

11

proceedings, power of sale, or any other legal right, remedy or recourse, the title to and right of possession of any such property shall pass to the purchaser thereof, and to the fullest extent permitted by law, the Mortgagor shall be completely and irrevocably divested of all of its right, title, interest, claim, equity, equity of redemption, and demand whatsoever, either at law or in equity, in and to the property sold and such sale shall be a perpetual bar both at law and in equity against the Mortgagor, and against all other Persons claiming or to claim the property sold or any part thereof, by, through or under Mortgagor.

(b) In case of any sale of any Mortgaged Property, any holder of Mortgage Bonds or the Mortgagee, may bid for and purchase any Mortgaged Property, and, upon compliance with the terms of sale, may hold, retain, possess and dispose of such Mortgaged Property in absolute right of such holder or the Mortgagee, without further accountability, and shall be entitled, for the purpose of making settlement or payment for the Mortgaged Property purchased, to use and apply any Mortgage Bonds by presenting such Mortgage Bonds, in order that there may be credited thereon the sum apportionable and applicable thereto out of the net proceeds of such sale; and thereupon such purchaser shall be credited on account of such purchase price, with the sum apportionable and applicable out of such net proceeds to the payment of or as credit on the outstanding Mortgage Bonds so presented.

(c) From time to time the Mortgagee, or other person acting in any sale of Mortgaged Property to be made under this Mortgage, may adjourn such sale by announcement at the time and place appointed for such sale or for such adjourned sale or sales; and without further notice or publication, such sale may be made at the time and place to which such sale shall be so adjourned.

(d) Upon the completion of any sale of any Mortgaged Property under or by virtue of this Mortgage, the Mortgagee shall execute and deliver on behalf of the Mortgagor and itself, as Mortgagee, to the purchaser a sufficient deed or other instruments conveying, assigning and transferring such Mortgaged Property free from the lien of this Mortgage. The Mortgagee and its successors are hereby appointed the attorneys of the Mortgagor, in its name and stead, to make all necessary conveyances, assignments and transfers of Mortgaged Property, including customary representations and warranties, and for that purpose may execute all necessary deeds and instruments of conveyance, assignment and transfer, and may substitute one or more persons with similar power, the Mortgagor hereby ratifying and confirming all that its attorneys, or such substitute or substitutes, shall do by virtue hereof. Nevertheless, the Mortgagor, if so requested by the Mortgagee, shall join in the execution and delivery of such conveyances, assignments and transfers. Any such sale of Mortgaged Property made under or by virtue of this Mortgage; whether under the power of sale herein granted or pursuant to judicial proceedings, shall be deemed to have been sold at a commercially reasonable price and shall operate to divest all right, title, interest, claim and demand, either at law or in equity, of the Mortgagor and the Mortgagee hereunder, in and to the Mortgaged Property sold, and shall be a perpetual bar, both at law and in equity, against the Mortgagor, its successors and assigns, and against any and all persons claiming or to claim the Mortgaged Property sold or any part thereof, from, through or under the Mortgagor or its successors or assigns or this Mortgage.

(e) The Mortgaged Property may be sold subject to unpaid taxes and Permissible Encumbrances, and, after deducting all costs, fees and expenses of the Mortgagee (including costs of evidence of title in connection with the sale), the Mortgagee or an officer that makes any sale shall apply the proceeds of sale in the manner set forth in Section 2.07.

12

(f) Any foreclosure or other sale of less than the whole of the Mortgaged Property or any defective or irregular sale made hereunder shall not exhaust the power of foreclosure or of sale provided for herein; and subsequent sales may be made hereunder until the Secured Obligations have been satisfied, or the entirety of the Mortgaged Property has been sold.

(g) If an Event of Default shall occur and be continuing, the Mortgagee may instead of, or in addition to, exercising the rights described in Section 2.05(a) above and either with or without entry or taking possession as herein permitted, proceed by a suit or suits in law or in equity or by any other appropriate proceeding or remedy (i) to specifically enforce the performance of any term, covenant, condition or agreement of this Mortgage or any other right, or (ii) to pursue any other remedy available to the Mortgagee under applicable law, all as the Mortgagee shall determine most effectual for such purposes.

SECTION 2.06. Other Remedies. (a) In case an Event of Default shall occur and be continuing, the Mortgagee may also exercise, to the extent not prohibited by law, any or all of the remedies available to a secured party under the UCC, rights and recourses granted in the Mortgage Bond Indenture and the Collateral Trust Agreement and available at law or in equity (including under the UCC), which rights (a) shall be cumulative and concurrent, (b) may be pursued separately, successively or concurrently against the Mortgagor under the Mortgage Bond Indenture, or against the Mortgaged Property, or against any one or more of them, at the sole discretion of Mortgagee, (c) may be exercised as often as occasion therefor shall arise, and the exercise or failure to exercise any of them shall not be construed as a waiver or release thereof or of any other right, remedy or recourse, and (d) are intended to be, and shall be, nonexclusive. No action by Mortgagee in the enforcement of any rights, remedies or recourses under the Mortgage Bond Indenture or otherwise at law or equity shall be deemed to cure any Event of Default.

(b) In connection with a sale of the Mortgaged Property or any personal property and the application of the proceeds of sale as provided in Section 2.07, the Mortgagee shall be entitled to enforce payment of and to receive up to the principal amount of the Secured Obligations, plus all other charges, payments and costs due under this Mortgage, and to recover a deficiency judgment for any portion of the aggregate principal amount of the Secured Obligations remaining unpaid, with interest.

SECTION 2.07. Application of Sale Proceeds. (a) If an Event of Default shall have occurred and be continuing, at any time at the Mortgagee’s election, the Mortgagee may apply all or any part of the net cash proceeds of Shared Collateral realized through the exercise by the Mortgagee of its remedies hereunder, whether or not held in any Collateral Account, in payment of the Secured Obligations as provided in the Collateral Trust Agreement.

(b) The Mortgagee shall have absolute discretion as to the time of application of any such proceeds, moneys or balances in each case in accordance with and subject to the requirements of the Collateral Trust Agreement. The receipt by the Mortgagee or other authorized person of money paid for the purchase of Mortgaged Property shall be a sufficient discharge to any purchaser of such Mortgaged Property; and no such purchaser or the

13

representative, grantee or assignee of such purchaser, after paying such purchase money and receiving such receipt, shall be affected by, or in any manner answerable for, any loss, misapplication or non-application of such purchase money, or be bound to inquire as to the authorization, necessity, expediency or regularity of such sale.

SECTION 2.08. Mortgagor as Tenant Holding Over. If the Mortgagor remains in possession of any of the Mortgaged Property after any foreclosure sale by the Mortgagee, at the Mortgagee’s election the Mortgagor shall be deemed a tenant holding over and shall forthwith surrender possession to the purchaser or purchasers at such sale or be summarily dispossessed or evicted, forcibly or otherwise, with or without process of law, according to provisions of law applicable to tenants holding over.

SECTION 2.09. Waiver of Appraisement, Valuation, Stay, Extension and Redemption Laws. The Mortgagor waives, to the extent not prohibited by law, (a) the benefit of all laws now existing or that hereafter may be enacted (i) providing for any appraisement or valuation of any portion of the Mortgaged Property and/or (ii) in any way extending the time for the enforcement or the collection of amounts due under any of the Secured Obligations or creating or extending a period of redemption from any sale made in collecting such debt or any other amounts due the Mortgagee; (b) any right to at any time insist upon, plead, claim or take the benefit or advantage of any law now or hereafter in force providing for any homestead exemption, stay, statute of limitations, extension or redemption, or sale of the Mortgaged Property as separate tracts, units or estates or as a single parcel in the event of foreclosure or notice of deficiency; and (c) all rights of redemption (both statutory and equitable), valuation, appraisement, stay of execution, notice of election to mature or declare due the whole of or each of the Secured Obligations and marshaling in the event of foreclosure of this Mortgage.

SECTION 2.10. Discontinuance of Proceedings. In case the Mortgagee shall have proceeded to enforce any right under this Mortgage by foreclosure, entry or otherwise, and such proceeding shall have been discontinued or abandoned because of a waiver, or for any other reason, or shall have been determined adversely to the Mortgagee, then and in every such case the Mortgagor and the Mortgagee shall be restored to their former positions and rights hereunder in respect of the Mortgaged Property; and all rights, remedies and powers of the Mortgagee shall continue as though no such proceeding had been taken, but no such discontinuance or abandonment shall waive any Event of Default which may then exist or the right of the Mortgagee thereafter to exercise any right, remedy or recourse under the Mortgage Bond Indenture or Collateral Trust Agreement for such Event of Default.

SECTION 2.11. Suits to Protect the Mortgaged Property. The Mortgagee shall have power to institute and to maintain such suits and proceedings as it may be advised shall be necessary or expedient to prevent any impairment of the lien of this Mortgage by any acts of the Mortgagor, or of others, in violation of this Mortgage or which are unlawful, or as the Mortgagee may be advised shall be necessary or expedient to preserve and to protect its interests and the security and interests of the holders of the Mortgage Bonds, 2002 Indenture Notes and 2006 Indenture Notes in respect of the Mortgaged Property, or in respect of the income, earnings, rents, issues and profits thereof, including power to institute and to maintain suits or proceedings to restrain the enforcement of, or compliance with, or the observance of, any legislative or other governmental enactment, rule or order which may be unconstitutional or otherwise invalid, if the

14

enforcement of, or compliance with, or observance of, such enactment, rule or order would impair the lien of this Mortgage or be prejudicial to the interests of the Mortgage Bonds, 2002 Indenture Notes, 2006 Indenture Notes or the Mortgagee, provided that the Mortgagee shall have no obligation to exercise such power.

SECTION 2.12. Possession by Mortgagee. Notwithstanding the appointment of any receiver, liquidator or trustee of the Mortgagor, any of its property or the Mortgaged Property, the Mortgagee shall be entitled, to the extent not prohibited by law, to remain in possession and control of all parts of the Mortgaged Property now or hereafter granted under this Mortgage to the Mortgagee in accordance with the terms hereof and applicable law.

SECTION 2.13. Waiver. (a) No delay or failure by the Mortgagee to exercise any right, power or remedy accruing upon any breach or Event of Default shall exhaust or impair any such right, power or remedy or be construed to be a waiver of any such breach or Event of Default or acquiescence therein; and every right, power and remedy given by this Mortgage to the Mortgagee may be exercised from time to time and as often as may be deemed expedient by the Mortgagee. No consent or waiver by the Mortgagee to or of any breach or Event of Default by the Mortgagor in the performance of the Secured Obligations shall be deemed or construed to be a consent or waiver to or of any other breach or Event of Default in the performance of the same or of any other Secured Obligations by the Mortgagor hereunder. No failure on the part of the Mortgagee to complain of any act or failure to act or to declare an Event of Default, irrespective of how long such failure continues, shall constitute a waiver by the Mortgagee of its rights hereunder or impair any rights, powers or remedies consequent on any future Event of Default by Mortgagor.

(b) Even if the Mortgagee (i) grants some forbearance or an extension of time for the payment of any sums secured hereby, (ii) takes other or additional security for the payment of any sums secured hereby, (iii) waives or does not exercise some right granted herein, (iv) releases a part of the Mortgaged Property from this Mortgage, (v) agrees to change some of the terms, covenants, conditions or agreements of the Mortgage Bond Indenture, (vi) consents to the filing of a map, plat or replat affecting the Mortgaged Property, (vii) consents to the granting of an easement or other right affecting the Mortgaged Property or (viii) makes or consents to an agreement subordinating the Mortgagee’s lien on the Mortgaged Property hereunder; no such act or omission shall preclude the Mortgagee from exercising any other right, power or privilege herein granted or intended to be granted in the event of any breach or Event of Default then made or of any subsequent default; nor, except as otherwise expressly provided in an instrument executed by the Mortgagee, shall this Mortgage be altered thereby. In the event of the sale or transfer by operation of law or otherwise of all or part of the Mortgaged Property, the Mortgagee is hereby authorized and empowered to deal with any vendee or transferee with reference to the Mortgaged Property secured hereby, or with reference to any of the terms, covenants, conditions or agreements hereof, as fully and to the same extent as it might deal with the original parties hereto and without in any way releasing or discharging any liabilities, obligations or undertakings.

SECTION 2.14. Mortgagee May File Proofs of Claims . The Mortgagee may file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Mortgagee and of the holders of the Mortgage Bonds, 2002 Indenture Notes or

15

2006 Indenture Notes allowed in any judicial proceedings relative to the Mortgagor, its creditors or Mortgaged Property. Nothing contained in this Mortgage shall be deemed to authorize the Mortgagee to authorize or consent to or accept or adopt on behalf of any holder of Mortgage Bonds, 2002 Indenture Notes or 2006 Indenture Notes, any plan of reorganization, arrangement, adjustment or composition affecting the Mortgage Bonds, 2002 Indenture Notes, 2006 Indenture Notes or any holder thereof, or to authorize the Mortgagee to vote in respect of the claim of any holder of Mortgage Bonds, 2002 Indenture Notes or 2006 Indenture Notes in any such proceeding.

All rights of action under this Mortgage may be enforced by the Mortgagee without the possession of any Mortgage Bond, 2002 Indenture Note or 2006 Indenture Note or the production thereof at trial or other proceedings relative thereto, and any such suit or proceedings instituted by the Mortgagee shall be brought in its own name, and any recovery of judgment shall be for the ratable benefit of the holders of the Mortgage Bonds, 2002 Indenture Notes or 2006 Indenture Notes.

SECTION 2.16. Payment of Litigation Expenses . Each holder of any Mortgage Bond or any Equal and Ratable Note, its acceptance hereof shall be deemed to have agreed, that any court may in its discretion require, in any suit for the enforcement of any right or remedy under this Mortgage, or in any suit against the Mortgagee for any action taken or omitted by it as Mortgagee, the filing by any party litigant in such suit of an undertaking to pay the costs of such suit, and that such court may in its discretion assess costs, including attorneys’ fees, against any party litigant in such suit, having due regard to the merits and good faith of the claims or defenses made by such party litigant; but this Section 2.19 shall not apply to any suit instituted by the Mortgagee, to any suit instituted by any holders having more than 10% in aggregate principal amount of outstanding Mortgage Bonds, 2002 Indenture Notes or 2006 Indenture Notes, or to any suit instituted by any holder for the enforcement of the payment of the principal of, premium, if any, or interest, if any, on any Mortgage Bond, 2002 Indenture Note or 2006 Indenture Note on or after the respective due dates expressed therein.
