number not contemporaneously outstanding, in exchange and substitution for the mutilated Note, or in lieu of and in substitution for the Note so destroyed, lost or stolen. In every case the applicant for a substituted Note shall furnish to the Company, the Trustee and any paying agent or Authenticating Agent such security or indemnity as may be required by them to save each of them harmless, and, in every case of destruction, loss or theft of a Note, the applicant shall also furnish to the Company and to the Trustee evidence to their satisfaction of the destruction, loss or theft of such Note and of the ownership thereof.

(b)           The Trustee shall authenticate any such substituted Note and deliver the same upon the written request or authorization of any officer of the Company. Upon the issuance of any substituted Note, the Company may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses connected therewith. If any Note which has matured, is about to mature or has been called for redemption shall become mutilated or be destroyed, lost or stolen, the Company may, instead of issuing a substituted Note, pay or authorize the payment of the same (without surrender thereof except in the case of a mutilated Note) if the applicant for such payment shall furnish to the Company, the Trustee and any paying agent or Authenticating Agent such security or indemnity as may be required by them to save each of them harmless and, in case of destruction, loss or theft, evidence satisfactory to the Company and the Trustee of the destruction, loss or theft of such Note and of the ownership thereof.

Temporary Notes shall be issuable in any authorized denomination and substantially in the form of the definitive Notes but with such omissions, insertions and variations as may be appropriate for temporary Notes, all as may be determined by the Company. Every such temporary Note shall be authenticated by the Trustee upon the same conditions and in substantially the same manner, and with the same effect, as the definitive Notes.

Such exchange shall be made by the Company at its own expense and without any charge therefor to the Noteholders. Until so exchanged, the temporary Notes of such series shall in all respects be entitled to the same

14

benefits under this Indenture as definitive Notes of such series authenticated and delivered hereunder.

Section 2.11           Special Record Date.  If and to the extent that the Company fails to make timely payment or provision for timely payment of interest on any series of Notes (other than on an Interest Payment Date that is a Maturity date), that interest shall cease to be payable to the Persons who were the Noteholders of such series at the applicable Regular Record Date. In that event, when moneys become available for payment of the interest, the Trustee shall (a) establish a date of payment of such interest and a Special Record Date for the payment of that interest, which Special Record Date shall be not more than 15 or fewer than 10 days prior to the date of the proposed payment and (b) mail notice of the date of payment and of the Special Record Date not fewer than 10 days preceding the Special Record Date to each Noteholder of such series at the close of business on the 15th day preceding the mailing at the address of such Noteholder, as it appeared on the register for the Notes. On the day so established by the Trustee the interest shall be payable to the Holders of the applicable Notes at the close of business on the Special Record Date.

Section 2.12           Payment Of Notes.  Payment of the principal of and interest and premium on all Notes shall be payable as follows:

As a

15

condition to the payment, at Maturity, of any part of the principal of, interest on and applicable premium of any Global Note, the Depositary shall surrender, or cause to be surrendered, such Global Note to the Trustee, whereupon a new Global Note shall be issued to the Depositary pursuant to Section 2.06(f) hereof.

(b)           With respect to any Note that is not a Global Note, principal, applicable premium and interest due at the Maturity of the Note shall be payable in immediately available funds when due upon presentation and surrender of such Note at the corporate trust office of the Trustee or at the authorized office of any paying agent in the Borough of Manhattan, The City and State of New York.

Subject to Article XIII hereof, all payments made by or on behalf of the Company to the Trustee on a series of Senior Note First Mortgage Bonds shall be deemed to be a payment by the Company pursuant to this Section 2.12 and shall be applied by the Trustee to pay, when due, principal of, premium, if any, and/or interest on the Related Series of Notes and, to the extent so applied, shall satisfy the Company’s obligations on such Notes. The Company shall cause payment to be made to the Trustee of principal of, premium, if any, and (if applicable) interest on a series of Senior Note First Mortgage Bonds in a manner and at a time that will enable the Trustee to make payments when due, of the principal of, premium, if any, and interest on the Related Series of Notes.

Section 2.13           Notes Issuable In The Form Of A Global Note.  (a)  If the Company shall establish pursuant to Section 2.05 hereof that the Notes of a particular series are to be issued in the form of one or more Global Notes, then the Company shall execute and the Trustee shall, in accordance with Section 2.05 hereof and the Company Order delivered to the Trustee thereunder, authenticate and deliver such Global Note or Notes, which, unless otherwise specified in such Company Order, (i) shall represent, shall be denominated in an amount equal to the aggregate principal amount of, and shall have the same terms as, the outstanding Notes of such series to be represented by such Global Note or Notes, (ii) shall be registered in the name of the Depositary or its nominee, (iii) shall be delivered by the Trustee to the Depositary or pursuant to the Depositary’s instruction and (iv) shall bear a legend substantially to the following effect: “This Note is a Global Note registered in the name of the Depositary (referred to herein) or a nominee thereof and, unless and until it is exchanged in whole for the individual Notes represented hereby as provided in the Indenture referred to below, this Global Note may not be transferred except as a whole by the Depositary to a nominee of the Depositary or by a nominee of the Depositary to the Depositary or another nominee of the Depositary or by the Depositary or any such nominee

16

to a successor Depositary or a nominee of such successor Depositary. Unless this Global Note is presented by an authorized representative of The Depository Trust Company (55 Water Street, New York, New York) to the Trustee for registration of transfer, exchange or payment, and any certificate issued is registered in the name of Cede & Co. or such other name as requested by an authorized representative of The Depository Trust Company and any payment is made to Cede & Co., any transfer, pledge or other use hereof for value or otherwise by or to any person is wrongful since the registered owner hereof, Cede & Co., has an interest herein” or such other legend as may be required by the rules and regulations of the Depositary.

(b)           (i)            If at any time the Depositary for a Global Note notifies the Company that it is unwilling or unable to continue as Depositary for such Global Note or if at any time the Depositary for the Global Note shall no longer be eligible or in good standing under the Securities Exchange Act of 1934, or other applicable statute or regulation, the Company shall appoint a successor Depositary with respect to such Global Note.

The Trustee shall not be charged with knowledge or notice of the ineligibility of a Depositary unless a Responsible Officer shall have actual knowledge thereof.

(ii)                                 (A)          The Company may at any time and in its sole discretion determine that all (but not less than all) outstanding Notes of a series issued or issuable in the form of one or more Global Notes shall no longer be represented by such Global Note or Notes. In such event the Company shall execute, and the Trustee, upon receipt of a Company Order for the authentication and delivery of individual Notes in exchange for such Global Note, shall authenticate and deliver individual Notes of like tenor and terms in definitive form in an aggregate principal amount equal to the principal amount of such Global Note or Notes in exchange for such Global Note or Notes.

(iii)              In any exchange provided for in any of the preceding two paragraphs, the Company will execute and the Trustee will authenticate and deliver individual Notes in definitive registered form in authorized denominations. Upon the exchange of a Global Note for individual Notes, such Global Note shall be cancelled by the Trustee. Notes issued in exchange for a Global Note pursuant to this Section shall be registered in such names and in such authorized denominations as the Depositary for such

17

Global Note, pursuant to instructions from its direct or indirect participants or otherwise, shall instruct the Trustee. The Trustee shall deliver such Notes to the Depositary for delivery to the persons in whose names such Notes are so registered, or if the Depositary shall refuse or be unable to deliver such Notes, the Trustee shall deliver such Notes to the persons in whose names such Notes are registered, unless otherwise agreed upon between the Trustee and the Company, in which event the Company shall cause the Notes to be delivered to the persons in whose names such Notes are registered.

The exchange contemplated in this subsection shall be consummated at least 30 days prior to any Interest Payment Date applicable to any of the Global Notes surrendered to the Trustee. Upon any exchange of any Global Note with two or more Original Issue Dates, whether pursuant to this Section or pursuant to Section 2.06 or Section 3.03 hereof, the aggregate principal amount of the Notes with a particular Original Issue Date shall be the same before and after such exchange, after giving effect to any retirement of Notes and the Original Issue Dates applicable to such Notes occurring in connection with such exchange.

The Company shall promptly notify the Trustee of any change in the “CUSIP” or “ISIN” numbers.

REMEDIES OF THE TRUSTEE AND NOTEHOLDERS
ON EVENTS OF DEFAULT

Section 8.01           Events Of Default. (a)  If one or more of the following Events of Default shall have occurred and be continuing:

(1)           default in the payment of any installment of interest upon any of the Notes as and when the same shall become due and payable, and continuance of such default for a period of sixty (60) days;

(2)           default in the payment of the principal of or any premium on any of the Notes as and when the same shall become due and payable;

(3)           failure on the part of the Company duly to observe or perform any other of the covenants or agreements on the part of the Company contained in this Indenture for a period of sixty (60) days after the date on which written notice specifying such failure, stating that such notice is a “Notice of Default” hereunder and demanding that the Company remedy the same, shall have been given to the Company by the Trustee by registered mail, or to the Company and the Trustee by the Holders of not less than 25% in aggregate principal amount of the Notes at the time outstanding;

(4)           prior to the Release Date, a completed default (as defined in the First Mortgage) has occurred and is continuing;  provided, however, that anything in this Indenture to the contrary notwithstanding, the waiver or cure of such default under the First Mortgage and the rescission and annulment of the consequences thereof under the First Mortgage shall constitute a waiver of the corresponding Event of Default hereunder and a rescission and annulment of the consequences thereof hereunder;

33

(5)           a court having jurisdiction in the premises shall enter a decree or order for relief in respect of the Company in an involuntary case under any applicable bankruptcy, insolvency or other similar law now or hereafter in effect, adjudging the Company a bankrupt or insolvent, or approving as properly filed a petition seeking reorganization, arrangement, adjustment or composition of or in respect of the Company under any applicable law, or appointing a receiver, liquidator, assignee, custodian, trustee or sequestrator (or similar official) of the Company or for any substantial part of the property of the Company, or ordering the winding up or liquidation of the affairs of the Company, and such decree or order shall remain unstayed and in effect for a period of sixty (60) consecutive days; or

(6)           the Company shall commence a voluntary case or proceeding under any applicable bankruptcy, insolvency, reorganization or other similar law now or hereafter in effect or any other case or proceeding to be adjudicated a bankrupt or insolvent, or consent to the entry of a decree or order for relief in an involuntary case under any such law, or to the commencement of any bankruptcy or insolvency case or proceeding against it, or the filing by it of a petition or answer or consent seeking reorganization or relief under any applicable law, or consent to the filing of such petition or to the appointment or taking possession by a receiver, liquidator, assignee, custodian, trustee or sequestrator (or similar official) of the Company or for any substantial part of the property of the Company, or make any general assignment for the benefit of creditors, or the notice by it in writing of its inability to pay its debts generally as they become due, or the taking of any corporate action by the Company in furtherance of any such action;

then, unless the principal of and interest on all of the Notes shall have already become due and payable, either the Trustee or the Holders of not less than 33% in aggregate principal amount of the Notes then outstanding, by notice in writing to the Company (and to the Trustee if given by such Holders), may declare the principal of and interest on all the Notes to be due and payable immediately and upon any such declaration the same shall become immediately due and payable, anything in this Indenture or in the Notes contained to the contrary notwithstanding and, upon the Notes being declared to be due and payable, the Trustee shall promptly file with the Mortgage Trustee a written demand for redemption of all Senior Note First Mortgage Bonds to the extent provided in the applicable provisions of the related supplemental indenture or indentures to the First Mortgage.

The foregoing paragraph, however, is subject to the condition that if, at any time after the principal of and interest on the Notes shall have been so declared due and payable, and before any judgment or decree for the payment of the moneys due shall have been obtained or entered as hereinafter provided, and prior to the acceleration of all of the First Mortgage Bonds issued and outstanding under the First Mortgage, the Company shall pay or shall deposit with the Trustee a sum sufficient to pay all matured installments of interest upon all of the Notes and the principal of and any premium on any and all Notes which shall have become due otherwise than by acceleration (with interest on overdue installments of interest, to the extent that payment of such interest is enforceable under applicable law, and on such principal and applicable premium at the rate borne by the Notes to the date of such payment or deposit) and all sums paid or advanced by the Trustee hereunder, the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under

34

Section 9.06 hereof, and any and all Events of Default, other than the non-payment of principal of and accrued interest on any Notes which shall have become due solely by acceleration of maturity, shall have been cured or waived (including any defaults under the First Mortgage, as evidenced by notice thereof from the Mortgage Trustee to the Trustee), then and in every such case such payment or deposit shall cause an automatic waiver of the Event of Default and its consequences (including, if given, the written demand for redemption of all Senior Note First Mortgage Bonds) and shall cause an automatic rescission and annulment of the acceleration of the Notes; but no such waiver or rescission and annulment shall extend to or shall affect any subsequent default, or shall impair any right consequent thereon.

(b)           If the Trustee shall have proceeded to enforce any right under this Indenture and such proceedings shall have been discontinued or abandoned because of such rescission or annulment or for any other reason or shall have been determined adversely to the Trustee, then and in every such case the Company and the Trustee shall be restored respectively to their several positions and rights hereunder, and all rights, remedies and powers of the Company and the Trustee shall continue as though no such proceeding had been taken.

Section 8.02           Collection Of Indebtedness By Trustee; Trustee May Prove Debt. (a)  The Company covenants that if an Event of Default described in clause (a)(1) or (a)(2) of Section 8.01 hereof shall have occurred and be continuing, then, upon demand of the Trustee, the Company shall pay to the Trustee, for the benefit of the Holders of the Notes, the whole amount that then shall have so become due and payable on all such Notes for principal or interest, as the case may be, with interest upon the overdue principal and any premium and (to the extent that payment of such interest is enforceable under applicable law) upon the overdue installments of interest at the rate borne by the Notes; and, in addition thereto, such further amounts as shall be sufficient to cover the costs and expenses of collection, including reasonable compensation to the Trustee, its agents, attorneys and counsel, any expenses or liabilities incurred by the Trustee hereunder other than through its negligence or willful misconduct. Until such demand is made by the Trustee, the Company may pay the principal of and interest on the Notes to the Holders, whether or not the Notes are overdue.

(b)           In case the Company shall fail forthwith to pay such amounts upon such demand, the Trustee, in its own name and as trustee of an express trust, shall be entitled and empowered to institute any actions or proceedings at law or in equity for the collection of the sums so due and unpaid, including, prior to the Release Date, to exercise any rights to that end it may have as a holder of Senior Note First Mortgage Bonds, and may enforce any such judgment or final decree against the Company or any other obligor on the Notes and collect in the manner provided by law out of the property of the Company or any other obligor on such Notes wherever situated, the moneys adjudged or decreed to be payable.

(c)           In case there shall be pending proceedings relative to the Company or any other obligor upon the Notes under Title 11 of the United States Code or any other applicable Federal or state bankruptcy, insolvency or other similar law, or in case a receiver, assignee or trustee in bankruptcy or reorganization, liquidator, sequestrator or similar official shall have been appointed for or taken possession of the Company or its property or such other obligor, or in case of any other comparable judicial proceedings relative to the Company or such other obligor, or to the creditors or property of the Company or such other obligor, the Trustee, irrespective of

35

whether the principal of the Notes shall then be due and payable as therein expressed or by declaration or otherwise and irrespective of whether the Trustee shall have made any demand pursuant to the provisions of this Section, shall be entitled and empowered, by intervention in such proceedings or otherwise:

(1)           to file and prove a claim or claims for the whole amount of the principal and interest owing and unpaid in respect of the Notes, and to file such other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including, prior to the Release Date, any claims of the Trustee as holder of Senior Note First Mortgage Bonds and including any amounts due to the Trustee under Section 9.06 hereof) and of the Noteholders allowed in any judicial proceedings relative to the Company or such other obligor, or to the creditors or property of the Company or such other obligor; and

(2)           to collect and receive any moneys or other property payable or deliverable on any such claims, and to distribute all amounts received with respect to the claims of the Noteholders and of the Trustee on their behalf; and any trustee, receiver, liquidator, custodian or other similar official is hereby authorized by each of the Noteholders to make payments to the Trustee, and, in the event that the Trustee shall consent to the making of the payments directly to the Noteholders, to pay to the Trustee such amounts due pursuant to Section 9.06 hereof.

(d)           Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or vote for or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Notes of any series or the rights of any Holder thereof, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding except to vote for the election of a trustee in bankruptcy or similar person.

(e)           All rights of action and of asserting claims under this Indenture, or under any of the Notes may be prosecuted and enforced by the Trustee without the possession of any of the Notes or the production thereof at any trial or other proceedings relative thereto, and any such action or proceedings instituted by the Trustee shall be brought in its own name as trustee of an express trust, and any recovery of judgment, subject to the payment of the expenses, disbursements and compensation of the Trustee and its agents, attorneys and counsel, shall be for the ratable benefit of the Holders of the Notes in respect of which such action was taken.

(f)            In any proceedings brought by the Trustee (and also any proceedings involving the interpretation of any provision of this Indenture to which the Trustee shall be a party), the Trustee shall be held to represent all the Holders of the Notes in respect to which action was taken, and it shall not be necessary to make any Holders of such Notes parties to any such proceedings.

Section 8.03           Application Of Proceeds. Any moneys collected by the Trustee with respect to any of the Notes pursuant to this Article shall be applied in the following order, at the date or dates fixed by the Trustee for the distribution of such moneys, upon presentation of the

36

several Notes, and stamping thereon the payment, if only partially paid, and upon surrender thereof if fully paid.

SECOND: In case the principal of the outstanding Notes in respect of which such moneys have been collected shall not have become due and be unpaid, to the payment of interest on the Notes, in the order of the maturity of the installments of such interest, with interest (to the extent allowed by law) upon the overdue installments of interest at the rate borne by the Notes, such payments to be made ratably to the persons entitled thereto, and then to the payment to the Holders entitled thereto of the unpaid principal of and applicable premium on any of the Notes which shall have become due (other than Notes previously called for redemption for the payment of which moneys are held pursuant to the provisions of this Indenture), whether at stated maturity or by redemption, in the order of their due dates, beginning with the earliest due date, and if the amount available is not sufficient to pay in full all Notes due on any particular date, then to the payment thereof ratably, according to the amounts of principal and applicable premium due on that date, to the Holders entitled thereto, without any discrimination or privilege;

THIRD: In case the principal of the outstanding Notes in respect of which such moneys have been collected shall have become due, by declaration or otherwise, to the payment of the whole amount then owing and unpaid upon the Notes for principal and any premium and interest thereon, with interest on the overdue principal and any premium and (to the extent allowed by law) upon overdue installments of interest at the rate borne by the Notes; and in case such moneys shall be insufficient to pay in full the whole amount so due and unpaid upon the Notes, then to the payment of such principal and any premium and interest without preference or priority of principal and any premium over interest, or of interest over principal and any premium or of any installment of interest over any other installment of interest, or of any Note over any other Note, ratably to the aggregate of such principal and any premium and accrued and unpaid interest; and

FOURTH: To the payment of the remainder, if any, to the Company or its successors or assigns, or as a court of competent jurisdiction may determine.

Section 8.04           Limitations On Suits By Noteholders. (a)  No Holder of any Note shall have any right by virtue of or by availing of any provision of this Indenture to institute any suit, action or proceeding in equity or at law upon or under or with respect to this Indenture or for the appointment of a receiver or trustee, or for any other remedy hereunder, unless such Holder previously shall have given to the Trustee written notice of an Event of Default with respect to such Note and of the continuance thereof, as hereinabove provided, and unless also Noteholders of a majority in aggregate principal amount of the Notes then outstanding affected by such Event of Default shall have made written request upon the Trustee to institute such action, suit or proceeding in its own name as Trustee hereunder and shall have offered to the Trustee such reasonable indemnity as it may require against the costs, expenses and liabilities to be incurred therein or thereby, and the Trustee for 60 days after its receipt of such notice, request and offer of indemnity, shall have neglected or refused to institute any such action, suit or proceeding; it being understood and intended, and being expressly covenanted by the taker and Holder of every

37

Note with every other taker and Holder and the Trustee, that no one or more Holders of Notes shall have any right in any manner whatever by virtue or by availing of any provision of this Indenture to affect, disturb or prejudice the rights of any other Holder of Notes, or to obtain or seek to obtain priority over or preference to any other such Holder or to enforce any right under this Indenture, except in the manner herein provided and for the equal, ratable and common benefit of all Holders of Notes. For the protection and enforcement of the provisions of this Section, each and every Noteholder and the Trustee shall be entitled to such relief as can be given either at law or in equity.

(b)           Notwithstanding any other provision in this Indenture, however, the rights of any Holder of any Note to receive payment of the principal of and any premium and interest on such Note, on or after the respective due dates expressed in such Note or on the applicable redemption date, or to institute suit for the enforcement of any such payment on or after such respective dates are absolute and unconditional, and shall not be impaired or affected without the consent of such Holder.

Section 8.05           Suits For Enforcement. In case an Event of Default has occurred, has not been waived and is continuing, hereunder the Trustee may in its discretion proceed to protect and enforce the rights vested in it by this Indenture, including, prior to the Release Date, its rights as holder of the Senior Note First Mortgage Bonds, by such appropriate judicial proceedings as the Trustee shall deem necessary to protect and enforce any of such rights, either by suit in equity or by action at law or by proceeding in bankruptcy or otherwise, whether for the specific enforcement of any covenant or agreement contained in this Indenture or in aid of the exercise of any power granted to it under this Indenture, or to enforce any other legal or equitable right vested in the Trustee by this Indenture or by law.

Section 8.06           Powers And Remedies Cumulative; Delay Or Omission Not Waiver Of Default. No right or remedy herein conferred upon or reserved to the Trustee or to the Holders of Notes is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted by law, be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right or remedy.

No delay or omission of the Trustee or of any Holder of Notes to exercise any right or power accruing upon any Event of Default occurring and continuing as aforesaid shall impair any such right or power or shall be construed to be a waiver of any such Event of Default or an acquiescence therein; and, subject to Section 8.04, every right and power given by this Indenture or by law to the Trustee or to the Holders of Notes may be exercised from time to time, and as often as shall be deemed expedient, by the Trustee or by the Holders of Notes, as the case may be.

Section 8.07           Direction of Proceedings and Waiver of Defaults By Majority of Noteholders. (a)  The Holders of a majority in aggregate principal amount of the Notes at the time outstanding shall have the right to direct the time, method, and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred on the Trustee; provided, that such direction shall not be otherwise than in accordance with law and

38

the provisions of this Indenture; and provided further that (subject to Section 9.01 hereof) the Trustee shall have the right to decline to follow any such direction if the Trustee being advised by counsel determines that the action or proceeding so directed may not lawfully be taken or if the Trustee in good faith by a trust committee of directors or trustees or responsible officers shall determine that the action or proceeding so directed would involve the Trustee in personal liability. Nothing in this Indenture shall impair the right of the Trustee in its discretion to take any action deemed proper by the Trustee and which is not inconsistent with such direction or directions by Noteholders.

(b)           The Holders of a majority in aggregate principal amount of the Notes at the time outstanding may on behalf of all of the Holders of the Notes waive any past default or Event of Default hereunder and its consequences except a default in the payment of principal of or any premium or interest on the Notes. Upon any such waiver the Company, the Trustee and the Holders of the Notes shall be restored to their former positions and rights hereunder, respectively, but no such waiver shall extend to any subsequent or other default or Event of Default or impair any right consequent thereon. Upon any such waiver, such default shall cease to exist and be deemed to have been cured and not to be continuing, and any Event of Default arising therefrom shall be deemed to have been cured and not to be continuing, for every purpose of this Indenture; but no such waiver shall extend to any subsequent or other default or Event of Default or impair any right consequent thereon.

Section 8.08           Notice of Default. The Trustee shall, within 90 days after the occurrence of a default with respect to the Notes, give to all Holders of the Notes, in the manner provided in Section 15.10, notice of such default actually known to the Trustee, unless such default shall have been cured or waived before the giving of such notice, the term “default” for the purpose of this Section 8.08 being hereby defined to be any event which is or after notice or lapse of time or both would become an Event of Default; provided that, except in the case of default in the payment of the principal of or any premium or interest on any of the Notes, or in the payment of any sinking or purchase fund installments, the Trustee shall be protected in withholding such notice if and so long as a trust committee of directors or trustees or responsible officers in good faith determines that the withholding of such notice is in the interests of the Holders of the Notes.

Section 8.09           Undertaking To Pay Costs. All parties to this Indenture agree, and each Holder of any Note by acceptance thereof 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 Indenture or in any suit against the Trustee for any action taken, suffered or omitted by it as Trustee, 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 reasonable costs, including reasonable attorneys’ fees and expenses, 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 8.09 shall not apply to any suit instituted by the Trustee, or to any suit instituted by any Noteholder, or group of Noteholders, holding in the aggregate more than 10% in principal amount of the Notes outstanding, or to any suit instituted by any Noteholder for the enforcement of the payment of the principal of or any premium or interest on any Note on or after the due date expressed in such Note or the applicable redemption date.

39

Section 8.10           Restoration of Rights on Abandonment of Proceedings. In case the Trustee or any Holder shall have proceeded to enforce any right under this Indenture and such proceedings shall have been discontinued or abandoned for any reason, or shall have been determined adversely to the Trustee or to such Holder, then, and in every such case, the Company, the Trustee and the Holders shall be restored respectively to their former positions and rights hereunder, and all rights, remedies and powers of the Company, the Trustee and the Holders shall continue as though no such proceedings had been taken.

Section 8.11           Defaults Under The First Mortgage. In addition to every other right and remedy provided herein, the Trustee may exercise any right or remedy available to the Trustee in its capacity as owner and holder of Senior Note First Mortgage Bonds which arises as a result of a completed default under the First Mortgage whether or not an Event of Default under this Indenture shall then have occurred and be continuing.

Section 8.12           Waiver of Usury, Stay or Extension Laws. The Company covenants (to the extent that it may lawfully do so) that it will not at any time insist upon, or plead, or in any manner whatsoever claim or take the benefit or advantage of, any usury, stay or extension law wherever enacted, now or at any time hereafter in force, which may affect the covenants or the performance of this Indenture; and the Company (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such law and covenants that it will not hinder, delay or impede the execution of any power herein granted to the Trustee, but will suffer and permit the execution of every such power as though no such law had been enacted.

(A)          the duties and obligations of the Trustee shall be determined solely by the express provisions of this Indenture, and the Trustee shall not be liable except for the performance of such duties and obligations as are specifically set forth in this Indenture, and no implied covenants or obligations shall be read into this Indenture against the Trustee; and

(c)           No provision of this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur any financial liability in the performance of any of its duties hereunder, or in the exercise of any of its rights or powers, if it shall have reasonable grounds for believing that repayment of such funds or adequate indemnity against such risk or liability is not reasonably assured to it.

(d)           the Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this Indenture at the request, order or direction of any of the Noteholders, pursuant to this Indenture, unless such Noteholders shall have offered to the Trustee reasonable security or indemnity satisfactory to it against the costs, expenses and liabilities which may be incurred by such exercise;

(g)           the Trustee may execute any of the trusts or powers hereunder or perform any duties hereunder either directly or through agents or attorneys; provided that the Trustee shall not be liable for the conduct or acts of any such agent or attorney that shall have been appointed in accordance herewith with due care;

The Company also covenants to fully indemnify each of the Trustee or any predecessor and their agents for, and to hold it harmless against, any loss, liability, claim, damage or expense incurred without negligence or willful misconduct on the part of the Trustee and arising out of or in connection with the acceptance or administration of this trust, including the costs and expenses of defending itself against any claim or liability.

If an Event of Default shall occur and be continuing, the principal of and interest on the Notes may be declared due and payable in the manner and with the effect provided in the Indenture and, upon such declaration, the Trustee shall demand the redemption of the Senior Note First Mortgage Bonds to the extent provided in the Indenture.
