TITLE, FORM AND TERMS OF THE FIRST MORTGAGE BONDS

Section 2.01 Title of the First Mortgage Bonds. This First Supplemental Indenture hereby creates a series of Securities designated as the “9.50% First Mortgage Bonds, due 2019, Series 2009A” (the “First Mortgage Bonds”) and such Securities shall be executed, authenticated and delivered in accordance with the provisions of, and, except as hereinafter provided, shall in all respects be subject to all of the terms, conditions and covenants of the Indenture as supplemented by this First Supplemental Indenture. For purposes of the Indenture, the First Mortgage Bonds shall constitute a single series of Securities and may be issued in an unlimited principal aggregate amount (subject to the limitations set forth in Article IV of the Indenture), although the initial issuance of the First Mortgage Bonds shall be in the principal amount of $265,500,000.

Section 2.02 Form and Terms of the First Mortgage Bonds. The form and terms of the First Mortgage Bonds pursuant to the authority granted by this First Supplemental Indenture in accordance with Sections 2.01 and 3.01 of the Indenture are set forth herein. The First Mortgage Bonds shall be issued in registered form without coupons in the denominations of $2,000 and integral multiples of $1,000 in excess thereof, appropriately numbered.

The First Mortgage Bonds shall mature on April 1, 2019 and shall bear interest at the rate of 9.50% per annum, payable semi-annually on the first (1st) day of April and the first (1st) day of October in each year commencing October 1, 2009 (each such April 1 and October 1 hereinafter called an “Interest Payment Date”).

If any Interest Payment Date falls on a day that is not a Business Day, the Interest Payment Date will be the next succeeding Business Day (and without any interest or payment in respect of any such delay). Interest will be computed on the basis of a 360-day year consisting of twelve 30-day months. The First Mortgage Bonds shall be payable as to principal and interest in any coin or currency of the United States of America which at the time of payment is legal tender for public and private debts, and shall be payable (as well the interest on the principal thereof) as provided for in the Indenture. The Company shall pay interest on overdue principal at the rate per annum borne by the First Mortgage Bonds, and it shall pay interest on overdue installments of interest at the rate per annum borne by the First Mortgage Bonds to the extent lawful.

The interest so payable on any Interest Payment Date shall be paid to the Persons in whose names the First Mortgage Bonds are registered at the close of business on the regular record date for such Interest Payment Date, which shall be the fifteenth (15th) day of the month

next preceding such Interest Payment Date (hereinafter called a “Regular Record Date”); except that if the Company shall default in the payment of any interest due on such Interest Payment Date, the Company may elect to make payment of any Defaulted Interest to the Persons in whose names the Securities of such series (or their respective Predecessor Securities) are registered at the close of business on a date (herein called a “Special Record Date”) to determine the Holders of record who will receive such Defaulted Interest (which shall be fixed in accordance with Section 3.07 of the Indenture), which Special Record Date shall not be more than fifteen (15) days or less than ten (10) days prior to the date proposed by the Company for payment of such Defaulted Interest.

Section 2.03 Optional Redemption. The Company, at its option, may redeem at any time all, or from time to time, any part of the First Mortgage Bonds, on not less than 30 days nor more than 60 days notice as provided in the Indenture (except that, notwithstanding the provisions of Section 5.04 of the Indenture, any notice of redemption for the First Mortgage Bonds given pursuant to said Section need not set forth the Redemption Price but only the manner of calculation thereof) at a Redemption Price equal to the greater of the following amounts:

(i)

100% of the principal amount of the First Mortgage Bonds then Outstanding to be so redeemed; and

(ii)

the sum of the present values of the principal amount and the remaining scheduled payments of interest on the First Mortgage Bonds to be redeemed (not including any portion of payments of interest accrued as of the applicable Redemption Date), discounted to the applicable Redemption Date in accordance with customary market practice on a semi-annual basis at a rate equal to the sum of the Treasury Rate plus 50 basis points,

plus, in either of the above cases, accrued and unpaid interest on the principal amount being redeemed to the applicable Redemption Date.

The Redemption Price will be calculated by the Independent Investment Banker assuming a 360-day year consisting of twelve 30-day months.

If less than all of the First Mortgage Bonds are to be redeemed, the Trustee shall select by lot, on a pro-rata basis or in such other manner as it shall deem appropriate and fair, the particular First Mortgage Bonds or portions thereof to be redeemed. Notice of redemption shall be given by mail not less than 30 nor more than 60 days prior to the Redemption Date to the Holders of First Mortgage Bonds to be redeemed (which, as long as the First Mortgage Bonds are held in the book-entry only system, will be The Depository Trust Company (or its nominee) or a successor Depositary); provided, however, that the failure to duly give such notice by mail, or any defect therein, shall not affect the validity of any proceedings for the redemption of First Mortgage Bonds as to which there shall have been no such failure or defect. Such notice may state that such redemption shall be conditional upon receipt by the Paying Agent or Agents for such First Mortgage Bonds, on or prior to the Redemption Date, of money sufficient to pay the principal of and premium, if any, and interest, if any, on such First Mortgage Bonds and that if such money shall not have been so received such notice shall be of no force or effect and the Company shall not be required to redeem such First Mortgage Bonds. On and after the

Redemption Date (unless the Company shall default in the payment of the First Mortgage Bonds or portions thereof to be redeemed at the applicable Redemption Price, together with interest accrued thereon to such date), interest on the First Mortgage Bonds or the portions thereof so called for redemption shall cease to accrue.

The Independent Investment Banker shall give to the Company and the Trustee written notice of the Redemption Price applicable to the First Mortgage Bonds promptly after its calculation thereof.

The Trustee shall be under no duty to inquire into, may conclusively presume the correctness of, shall be fully protected in relying upon the Independent Investment Banker’s calculation of any Redemption Price, and shall have no responsibility for such calculation.

(a) Each Global First Mortgage Bond initially shall: (i) be registered in the name of DTC or the nominee of DTC, (ii) be delivered to the First Mortgage Bond Custodian, and (iii) bear the appropriate legend, as set forth in Exhibit A.

The aggregate principal amount of each Global First Mortgage Bond may from time to time be increased or decreased by adjustments made on the records of the First Mortgage Bond Custodian, as provided in this First Supplemental Indenture.

(b) Members of, or participants in, DTC (“Agent Members”) shall have no rights under this First Supplemental Indenture with respect to any Global First Mortgage Bond held on their behalf by DTC or by the First Mortgage Bond Custodian under such Global First Mortgage Bond, and DTC may be treated by the Company, the Trustee, the Paying Agent and the Security Registrar and any of their agents as the absolute owner of such Global First Mortgage Bond for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the Company, the Trustee, the Paying Agent or the Security Registrar or any of their agents from giving effect to any written certification, proxy or other authorization furnished by DTC or impair, as between DTC and its Agent Members, the operation of customary practices of DTC governing the exercise of the rights of an owner of a beneficial interest in any Global First Mortgage Bond.

(c) Except as provided below, owners of beneficial interests in Global First Mortgage Bonds will not be entitled to receive Certificated First Mortgage Bonds. Certificated First Mortgage Bonds shall be issued to all owners of beneficial interests in a Global First Mortgage Bond in exchange for such interests if:

(ii) the Company executes and delivers to the Trustee and Security Registrar an Officers’ Certificate stating that such Global First Mortgage Bond shall be so exchangeable, or

(iii) an Event of Default has occurred and is continuing and the Security Registrar has received a written request from DTC to issue a Certificated First Mortgage Bond.

(d) In connection with the exchange of an entire Global First Mortgage Bond for Certificated First Mortgage Bonds pursuant to this paragraph (d), such Global First Mortgage Bond shall be deemed to be surrendered to the Trustee for cancellation, and the Company shall execute, and upon Company Order the Trustee shall authenticate and deliver, to each beneficial owner identified by DTC in exchange for its beneficial interest in such Global First Mortgage Bond, an equal aggregate principal amount of Certificated First Mortgage Bonds of authorized denominations.

(e) In connection with the exchange of a portion of a Certificated First Mortgage Bond for a beneficial interest in a Global First Mortgage Bond, the Trustee shall cancel such Certificated First Mortgage Bond, and the Company shall execute, and the Trustee shall authenticate and deliver to the exchanging Holder, a new Certificated First Mortgage Bond representing the principal amount not so exchanged.

Section 2.05 Restrictions on Transfer. The First Mortgage Bonds and any related documents may be amended or supplemented from time to time by the Company without the consent of any Holder to modify the restrictions on and procedures for resales and other transfers of the First Mortgage Bonds to reflect any change in applicable law or regulation (or the interpretation thereof) or in practices relating to the resale or transfer of restricted securities generally. Holders of the First Mortgage Bonds are deemed by the acceptance of such First Mortgage Bonds to have agreed to any such amendment or supplement.

Global First Mortgage Bonds offered and sold to Qualified Institutional Buyers (as such term is defined under Rule 144A) in the United States of America in reliance on Rule 144A (the “Rule 144A Global First Mortgage Bonds”) shall be issued in the form of permanent global First Mortgage Bonds substantially in the form attached hereto as Exhibit A containing the second legend set forth thereon (the “Restrictive Legend”) and the other legends required thereby and numbered from 1 upward with the prefix “RA”, deposited with the Trustee, as custodian for DTC, duly executed by the Company and authenticated by the Trustee as herein provided. The aggregate principal amount of the Rule 144A Global First Mortgage Bonds may from time to time be increased or decreased by adjustments made on the records of the Trustee, as custodian for DTC or its nominee, as hereinafter provided.

Global First Mortgage Bonds offered and sold outside the United States of America will be issued initially in the form of a single temporary Global First Mortgage Bond (the “Temporary Regulation S Global First Mortgage Bond”) and shall bear the Temporary Regulation S Global First Mortgage Bond Legend in the form set forth in Exhibit A. At any time following the Distribution Compliance Period, upon receipt by the Trustee and the Company of a duly executed certificate in the form of Exhibit A to the form of First Mortgage Bond, one or

more Global First Mortgage Bonds will be issued (together with the Temporary Regulation S Global First Mortgage Bonds, the “Regulation S Global First Mortgage Bonds”). The Regulation S Global First Mortgage Bonds shall be numbered from 1 upward with the prefix “RS”. The Regulation S Global First Mortgage Bond will be deposited upon issuance with the Trustee, as custodian for DTC, duly executed by the Company and authenticated by the Trustee as herein provided. The aggregate principal amount of the Regulation S Global First Mortgage Bonds may from time to time be increased or decreased by adjustments made on the records of the Trustee, as custodian for DTC or its nominee, as hereinafter provided.

The Trustee shall have no obligation or duty to monitor, determine or inquire as to compliance with any restrictions on transfer imposed under the Indenture, this First Supplemental Indenture or under applicable law with respect to any transfer of any beneficial interest in any Global First Mortgage Bond (including any transfers between or among Agent Members or beneficial owners in any Global First Mortgage Bond) other than to require delivery of such certificates and other documentation or evidence as are expressly required by, and to do so if and when expressly required by, the terms of the Indenture or this First Supplemental Indenture, and to examine the same to determine substantial compliance as to form with the express requirements hereof.

If the proposed transfer is a transfer of a beneficial interest in one Global First Mortgage Bond to a beneficial interest in another Global First Mortgage Bond, the Security Registrar shall reflect on its books and records the date and an increase in the principal amount of the Global First Mortgage Bond to which such interest is being transferred in an amount equal to the principal amount of the interest to be so transferred, and the Security Registrar shall reflect on its books and records the date and a corresponding decrease in the principal amount of the Global First Mortgage Bond from which such interest is being transferred.

A Global First Mortgage Bond may not be transferred as a whole except by the depository to a nominee of the depository or by a nominee of the depository to the depository or another nominee of the depository or by the depository or any such nominee to a successor depository or a nominee of such successor depository.

Beneficial interests in any restricted Global First Mortgage Bond may be transferred to Persons who take delivery thereof in the form of a beneficial interest in the same restricted Global First Mortgage Bond in accordance with the transfer restrictions set forth in the Restrictive Legend; provided, however, that prior to the expiration of the restricted period under the Securities Act, transfers of beneficial interests in the Regulation S Global First Mortgage Bond may not be made to a U.S. Person (as defined in Regulation S) or for the account or benefit of a U.S. Person (other than an Initial Purchaser).

Any Holder of a First Mortgage Bond requesting the transfer or exchange of a Rule 144A Global First Mortgage Bond (or an interest therein) for a Regulation S Global First Mortgage Bond (or an interest therein) must deliver or cause to be delivered to the Trustee a duly completed Regulation S Certificate, in the form attached as Exhibit A to the form of First Mortgage Bond; provided that if the requested transfer or exchange is made by the Holder of a First Mortgage Bond that does not bear a Restrictive Legend, then no certification is required.

Any Holder of a First Mortgage Bond requesting the transfer or exchange of a Regulation S Global First Mortgage Bond (or an interest therein) for a Rule 144A Global First Mortgage Bond (or an interest therein) must deliver or cause to be delivered to the Trustee a duly completed Rule 144A Certificate, in the form attached as Exhibit B to the form of First Mortgage Bond; provided that if the requested transfer or exchange is made by the Holder of a First Mortgage Bond that does not bear a Restrictive Legend, then no certification is required.

The Company shall issue a First Mortgage Bond that is not a Global First Mortgage Bond and that does not bear the Restrictive Legend in replacement of a First Mortgage Bond (that is not a Global First Mortgage Bond) bearing the Restrictive Legend at the request of any Holder following such request if (i) the Holder shall have obtained an opinion of counsel reasonably acceptable to the Company in form and substance reasonably satisfactory to the Company to the effect that the First Mortgage Bond may lawfully be disposed of without registration, qualification or legend pursuant to Rule 144, or (ii) the Holder sells the First Mortgage Bond pursuant to Rule 144 or an effective registration statement.

Beneficial interests in any unrestricted Global First Mortgage Bond may be transferred to Persons who take delivery thereof in the form of a beneficial interest in an unrestricted Global First Mortgage Bond.

[FORM OF REVERSE OF

9.50% FIRST MORTGAGE BOND, DUE 2019, SERIES 2009A]

This First Mortgage Bond is one of a duly authorized issue of First Mortgage Bonds of the Company (herein called the “First Mortgage Bonds”), unlimited in aggregate principal amount, of the series hereinafter specified, all issued and to be issued under and equally secured by an indenture, dated as of March 23, 2009, executed by the Company to The Bank of New York Mellon Trust Company, N.A. (herein called the “Trustee”) (said indenture being herein called the “Indenture”), to which Indenture and all indentures supplemental thereto (including the First Supplemental Indenture hereinafter referred to) reference is hereby made for a description of the properties mortgaged and pledged, the nature and extent of the security, the rights of the registered owners of the First Mortgage Bonds and of the Trustee in respect thereto, and the terms and conditions upon which the First Mortgage Bonds are, and are to be, secured, and for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders of the First Mortgage Bonds and of the terms upon which the First Mortgage Bonds are, and are to be, authenticated and delivered. To the extent permitted by, and as provided in, the Indenture, modifications or alterations of the Indenture, or of any indenture supplemental thereto, and of the rights and obligations of the Company and of the Holders of the First Mortgage Bonds may be made, in certain cases without the consent of the Holders of the First Mortgage Bonds, as set forth in Section 14.01 of the Indenture, and otherwise with the consent of the Company by an affirmative vote of not less than a majority in amount of the First Mortgage Bonds entitled to vote then outstanding, at a meeting of Holders of the First Mortgage Bonds called and held as provided in the Indenture, or by an affirmative vote of not less than a majority in amount of the First Mortgage Bonds of any series entitled to vote then outstanding and affected by such modifications or alterations, in case one or more but less than all of the series of First Mortgage Bonds then outstanding under the Indenture are so affected; provided, however, that no such modifications or alterations shall be made which will affect the terms of payment of the principal of, or interest on, this First Mortgage Bond, which are unconditional. The First Mortgage Bonds may be issued in series, for various principal sums, may mature at different times, may bear interest at different rates and may otherwise vary as provided in the Indenture. This First Mortgage Bond is one of a series designated as “9.50% First Mortgage Bonds, due 2019, Series 2009A” of the Company, issued under and secured by the Indenture and all indentures supplemental thereto and described in an indenture supplemental thereto (herein called the “First Supplemental Indenture”), dated as of March 23, 2009, executed by the Company to the Trustee.

The Company, at its option, may redeem all, or from time to time, any part of the First Mortgage Bonds of this series on not less than 30 days nor more than 60 days notice by first-class mail, postage prepaid as provided in the Indenture (except that, notwithstanding the provisions of Section 5.04 of the Indenture, any notice of redemption for the First Mortgage Bonds of this series given pursuant to said Section need not set forth the Redemption Price but only the manner of calculation thereof) at a Redemption Price equal to the greater of the following amounts:

(i)

100% of the principal amount of the First Mortgage Bonds of this series then Outstanding to be so redeemed; and

A-7

(ii)

the sum of the present values of the principal amount and the remaining scheduled payments of interest on the First Mortgage Bonds of this series to be redeemed (not including any portion of payments of interest accrued as of the applicable Redemption Date), discounted to the applicable Redemption Date in accordance with customary market practice on a semi-annual basis at a rate equal to the sum of the Treasury Rate plus 50 basis points,

plus, in either of the above cases, accrued and unpaid interest on the principal amount being redeemed to the applicable Redemption Date.

The Redemption Price for the First Mortgage Bonds of this series will be calculated by the Independent Investment Banker assuming a 360-day year consisting of twelve 30-day months. For purposes of calculating the Redemption Price pursuant to the foregoing optional redemption provisions, the following terms will have the meanings set forth below.

“Comparable Treasury Issue” means the U.S. Treasury security or securities selected by the Independent Investment Banker as having a maturity comparable to the remaining term of the First Mortgage Bonds to be redeemed that would be used, at the time of selection and in accordance with customary market practice, in pricing new issues of corporate debt securities of a comparable maturity to the remaining term of such First Mortgage Bonds.

“Comparable Treasury Price” means, with respect to any Redemption Date:

(i)

(ii)

if such release (or any successor release) is not published or does not contain such prices on such Business Day:

(x)

the average of the Reference Treasury Dealer Quotations for that Redemption Date, after excluding the highest and lowest of the Reference Treasury Dealer Quotations,

(y)

if the Trustee obtains fewer than four Reference Treasury Dealer Quotations, the average of all Reference Treasury Dealer Quotations so received, or

(z)

if only the Reference Treasury Dealer Quotation is received, such quotation.

“Independent Investment Banker” means one of the Reference Treasury Dealers selected by the Trustee after consultation with the Company.

“Reference Treasury Dealer” means each of four primary U.S. Government securities dealers in New York City (each a “Primary Treasury Dealer”), consisting of (i) X.X. Xxxxxx

A-8

Securities Inc. and (ii) three other nationally recognized investment banking firms (or their affiliates) that are selected by the Company in connection with the particular redemption, and their respective successors, provided that if any of them ceases to be a Primary Treasury Dealer, the Company will substitute another nationally recognized investment banking firm (or its affiliate) that is a Primary Treasury Dealer.

In the event of redemption of the First Mortgage Bonds of this series in part only, a new Security or First Mortgage Bonds of this series and of like tenor for the unredeemed portion hereof will be issued in the name of the Holder hereof upon the cancellation hereof.

The Indenture contains provisions for satisfaction and discharge of the entire indebtedness of the First Mortgage Bonds of this series.

In case an Event of Default shall occur, the principal of all the First Mortgage Bonds at any such time outstanding under the Indenture may be declared or may become due and payable, upon the conditions and in the manner and with the effect provided in the Indenture. The Indenture provides that such declaration may in certain events be waived by the Holders of a majority in principal amount of the First Mortgage Bonds outstanding.

[This First Mortgage Bond is a global First Mortgage Bond and will be exchangeable for Certificated First Mortgage Bonds of like series and terms and of differing authorized denominations in a like aggregate principal amount, only if (i) DTC notifies the Company that it is unwilling or unable to continue as depositary for such Global First Mortgage Bond and a successor depositary is not appointed by the Company within 90 days of such notice or DTC ceases to be a clearing agency registered under the Exchange Act at a time when DTC is required to be so registered in order to act as depositary, (ii) the Company executes and delivers to the Trustee and Security Registrar an Officers’ Certificate stating that such Global First Mortgage Bond shall be so exchangeable, or (iii) an Event of Default has occurred and is continuing and the Security Registrar has received a written request from DTC to issue a Certificated First Mortgage Bond. Upon any such exchange, Certificated First Mortgage Bonds of this series shall

A-9

be registered in the names of the beneficial owners of this First Mortgage Bond, which names shall be provided by DTC’s relevant Participants (as identified by DTC) to the Trustee.]2

No recourse shall be had for the payment of the principal of, or the interest on, this First Mortgage Bond, or for any claim based hereon or on the Indenture or any indenture supplemental thereto, against any incorporator, or against any stockholder, director or officer, past, present or future, of the Company, as such, or of any predecessor or successor corporation, either directly or through the Company or any such predecessor or successor corporation, whether for amounts unpaid on stock subscriptions or by virtue of any constitution, statute or rule of law, or by the enforcement of any assessment or penalty or otherwise, all such liability, whether at common law, in equity, by any constitution, statute or otherwise, of incorporators, stockholders, directors or officers being released by every owner hereof by the acceptance of this First Mortgage Bond and as part of the consideration for the issue hereof, and being likewise released by the terms of the Indenture.

This First Mortgage Bond is transferable by the registered owner hereof, in person or by duly authorized attorney, on the books of the Company to be kept for that purpose as provided for in the Indenture upon surrender and cancellation of this First Mortgage Bond and on presentation of a duly executed written instrument of transfer, and thereupon a new First Mortgage Bond or Bonds of the same series, of the same aggregate principal amount and in authorized denominations will be issued to the transferee or transferees in exchange therefor; and this First Mortgage Bond, with or without others of like series, may in like manner be exchanged for one or more new First Mortgage Bonds of the same series of other authorized denominations but of the same aggregate principal amount; all upon payment of the charges and subject to the terms and conditions set forth in the Indenture.

This First Mortgage Bond shall be subject to certain restrictions on transfer as set forth in the Indenture and the First Supplemental Indenture.

Any Holder of a First Mortgage Bond of this series requesting the transfer or exchange of a Rule 144A Global First Mortgage Bond (as defined in the First Supplemental Indenture) (or an interest therein) for a Regulation S Global First Mortgage Bond (as defined in the First Supplemental Indenture) (or an interest therein) must deliver or cause to be delivered to the Trustee a duly completed Regulation S Certificate, in the form attached as Exhibit A hereto; provided that if the requested transfer or exchange is made by the Holder of a First Mortgage Bond of this series that does not bear a Restrictive Legend (as defined in the First Supplemental Indenture), then no certification is required.
