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.

     

          
Section 2.04     Global First Mortgage Bond
Provisions.

    

    (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,

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.  The registered Holder of a Global First Mortgage Bond may grant
proxies and otherwise authorize any Person, including Agent Members and Persons
that may hold interests through Agent Members, to take any action that a Holder
is entitled to take under this First Supplemental Indenture, the Indenture or
the First Mortgage Bonds.

     

    (c)          
Except as

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.

     

    (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

Certificated First Mortgage Bond representing the principal amount not so
exchanged.

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

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.

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

Payment Date, which shall be the fifteenth (15th) day of the month next

interest shall be paid to the Holder of such First Mortgage Bond as of the close
of business on a date selected by the Trustee (in accordance with Section 3.07

    [FORM 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

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)

      release (or any successor release) published by The Wall Street Journal
      in the table entitled “Treasury Bonds, Notes, and Bills,” as
      determined by the Independent Investment Banker,
  or

            

    

     

    
      	
               
      

            	
              (ii)

              (z)

    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

nationally recognized investment banking firm (or its affiliate) that is a
Primary Treasury Dealer.

     

    “Reference
Treasury Dealer Quotations” means, with respect to each Reference Treasury
Dealer and any Redemption Date, the average, as determined by the Trustee, of
the bid and asked prices for the Comparable Treasury Issue (expressed as a

Reference Treasury Dealer at 3:30 p.m., New York City time, on the third
Business Day preceding that Redemption Date.

     

    “Treasury
Rate” means, with respect to any Redemption Date, the rate per year equal to the
semi-annual equivalent yield to maturity of the Comparable Treasury Issue,
calculated on the third Business Day preceding the applicable Redemption Date,

Date.

certain events be waived by the Holders of a majority in principal amount of the
First Mortgage Bonds outstanding.

    TITLE,
FORM AND TERMS OF THE COLLATERAL BONDS

     

    Section
2.01     Title of the Collateral
Bonds.  This Second Supplemental Indenture hereby creates a
series of Securities designated as the “First Mortgage Bonds, due 2014, Series
2009B” (which are referred to herein as the “Collateral Bonds”)
and the form thereof shall be substantially as set forth in Exhibit A
hereto.  Such Collateral Bonds 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 Second Supplemental
Indenture. For purposes of the Indenture, the Collateral Bonds shall constitute
a single series of Securities and may be issued in an unlimited aggregate
principal amount (subject to the limitations set forth in Article IV of the
Indenture), although the initial issuance of the Collateral Bonds shall be in
the aggregate principal amount of $50,000,000.

     

     

    Section
2.02     Form and Terms of the
Collateral Bonds.

     

    (a) The form
and terms of the Collateral Bonds pursuant to the authority granted by this
Second Supplemental Indenture in accordance with Sections 2.01 and 3.01 of the
Original Indenture are set forth herein.  The Collateral Bonds shall
be issued in registered form without coupons in the denominations of $1,000 and
integral multiples of $1,000, appropriately numbered and substantially in the
form set forth as Exhibit A
hereto.  The Collateral Bonds are to be issued to and registered in
the name of the Administrative Agent under the Credit Agreement, and are issued
as collateral security for any and all Borrower Obligations and Related Hedging
Obligations.

     

    (b) The
Collateral Bonds shall mature on the Maturity Date and shall bear interest at
the Interest Rate, payable on each Interest Payment Date.  The
Collateral 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 as otherwise provided for in the
Indenture.

     

     

    (c) The
obligation of the Company to make payments with respect to the principal of the
Collateral Bonds shall be fully or partially, as the case may be, satisfied and
discharged to the extent that, at the time that any such payment shall be due,
the portion of the Borrower Obligations constituting then due principal under
the Credit Agreement shall have been fully or partially paid or pre-paid in
immediately available funds.  Satisfaction of any obligation to the
extent that payment or pre-payment is made with respect to the Borrower
Obligations means that if any payment or pre-payment is made on the principal of
the Borrower Obligations under the Credit Agreement, a corresponding payment
obligation with respect to the principal of the Collateral Bonds shall be deemed
discharged in the same amount as the payment or pre-payment with respect to the
Borrower Obligations discharges the outstanding obligation with respect to such
Borrower Obligations.  Such full or partial payment or pre-payment of
principal of the Borrower Obligations shall automatically reduce the aggregate
principal amount of the Collateral Bonds, provided that, if at
the time of such full or partial payment or pre-payment all amounts

     

    
      
        
        

      

      
        5

        
          

        

      

      
        
        

      

    

    then due
in respect of the Related Hedging Obligations shall have not been paid in full
in immediately available funds, such automatic reduction of the aggregate
principal amount of the Collateral Bonds shall not be deemed to have occurred
until such time, if any, that the Company has paid or pre-paid all amounts then
due in respect of the Related Hedging Obligations.

     

    (d) The
obligation of the Company to make payments with respect to interest on the
Collateral Bonds shall be fully or partially, as the case may be, satisfied and
discharged to the extent that, at the time that any such payment shall be due,
the portion of the Borrower Obligations constituting then due interest and/or
fees under the Credit Agreement shall have been fully or partially
paid.  Satisfaction of any obligation to the extent that payment is
made with respect to the interest and/or fees under the Credit Agreement means
that if any payment is made on the interest and/or fees then comprising a
portion of the Borrower Obligations under the Credit Agreement, a corresponding
payment obligation with respect to the interest on the Collateral Bonds shall be
deemed discharged in the same amount as the payment with respect to the interest
and/or fees then comprising a portion of the Borrower Obligations under the
Credit Agreement discharges the outstanding obligation under the Credit
Agreement with respect to such interest and/or fees.

     

    (e) The
Trustee may at any time and all times conclusively presume that (i) the
obligation of the Company to make payments with respect to the principal of and
interest on the Collateral Bonds, so far as such payments at the time have
become due, has been fully satisfied and discharged unless and until a
Responsible Officer of the Trustee shall have received at the Corporate Trust
Office a written notice from the Administrative Agent stating (A) that
timely payment of principal and interest on the Collateral Bonds has not been
made, (B) that the Company is in arrears as to the payments required to be
made by it to the Administrative Agent pursuant to the Credit Agreement and
(C) the amount of the arrearage; and (ii) no Credit Repurchase Requirement
or Hedge Repurchase Requirement shall exist in respect of any Credit Repurchase
Date or Hedge Repurchase Date, as the case may be, unless and until a
Responsible Officer of the Trustee shall have received at the Corporate Trust
Office a copy of a Credit Notice or a Credit Written Demand or a copy of a Hedge
Notice or a Hedge Written Demand in respect of such Credit Repurchase
Requirement or Hedge Purchase Requirement, as the case may be.  This
paragraph is solely for the benefit of the Trustee.

     

    Section
2.03     Redemption;
Repurchase.

     

    (a)    
The
Collateral Bonds are not redeemable at the option of the Company.

     

    (b)     
(i) On a
Credit Repurchase Date, the Company shall repurchase (the “Credit Repurchase
Requirement”) an aggregate principal amount of the Collateral Bonds equal
to the lesser of, as of the applicable Credit Repurchase Date, (A) the Borrower
Obligations and (B) the Available Principal Amount (the “Credit Repurchase
Amount”).  On the Credit Repurchase Date, the Company will
deposit with the Trustee immediately available funds in an amount equal to the
Credit Repurchase Amount and the Trustee shall pay such amount as soon as
practicable after receipt thereof to the Administrative Agent upon surrender by
the Administrative Agent to the Trustee at the Corporate Trust Office of the
Trustee of Collateral Bonds in an aggregate 

     

    
      
        
        

      

      
        6

        
          

        

      

      
        
        

      

    

    principal
amount equal to the Credit Repurchase Amount, which surrender shall be a
condition to the Company’s Credit Repurchase Requirement.

     

    (ii)           Payment
of a Credit Repurchase Amount equal to the Borrower Obligations as of the
applicable Credit Repurchase Date shall be deemed to satisfy and discharge
principal of, and accrued and unpaid interest on, the Collateral Bonds in the
same amount as the amount of principal and accrued and unpaid interest,
respectively, comprising such Borrower Obligations.  Such satisfaction
and discharge shall automatically reduce the aggregate principal amount of the
Collateral Bonds by the aggregate amount of such Borrower Obligations comprising
principal.

     

    (iii)           Payment
of a Credit Repurchase Amount equal to the Available Principal Amount plus
accrued and unpaid interest on the Available Principal Amount, in each case, as
of the applicable Credit Repurchase Date shall be deemed to satisfy and
discharge all outstanding principal of and accrued and unpaid interest on the
Collateral Bonds as of such Credit Repurchase Date.

     

    (c)    
On a
Hedge Repurchase Date, the Company shall repurchase (the “Hedge Repurchase
Requirement”) an aggregate principal amount of the Collateral Bonds equal
to the lesser of, as of the applicable Hedge Repurchase Date, (A) the Settlement
Amount and (B) the Available Principal Amount (the “Hedge Repurchase
Amount”).  On the Hedge Repurchase Date, the Company will
deposit with the Trustee immediately available funds in an amount equal to the
Hedge Repurchase Amount and the Trustee shall pay such amount as soon as
practicable after receipt thereof to the Administrative Agent upon surrender by
the Administrative Agent to the Trustee at the Corporate Trust Office of the
Trustee of Collateral Bonds in an aggregate principal amount equal to the Hedge
Repurchase Amount, which surrender shall be a condition to the Company’s Hedge
Repurchase Requirement.

     

    (d)    
The
Company’s obligation to satisfy a Credit Repurchase Requirement or Hedge
Repurchase Requirement shall be mandatory upon, respectively, the occurrence of
a Credit Repurchase Event or a Hedge Repurchase Event.  Upon a Credit
Acceleration Event or a Hedge Acceleration Event, the Administrative Agent may,
at its option, deliver a Credit Written Demand or a Hedge Written Demand,
respectively, upon the Company’s receipt of which the Company’s compliance with
the Credit Repurchase Requirement or Hedge Repurchase Requirement, as
applicable, shall be mandatory.

     

    (e)    
Following
a Credit Repurchase Event or a Hedge Repurchase Event, the Administrative Agent
shall promptly deliver to the Company a Credit Notice or a Hedge Notice,
respectively.

     

    (f)    
A Credit
Written Demand, a Hedge Written Demand, a Credit Notice or a Hedge Notice, if
being made concurrently, may, but need not, be consolidated and form one
instrument.

     

    (g)    
Any
Collateral Bonds surrendered to the Trustee in connection with a Credit
Repurchase Requirement or Hedge Repurchase Requirement shall promptly be
cancelled in accordance with Section 3.09 of the Indenture.

    (h)    
Any
Collateral Bond which is to be repurchased only in part shall be surrendered at
a Place of Payment therefor (with, if the Company or the Trustee so requires,
due endorsement by, or a written instrument of transfer in form satisfactory to
the Company and the Trustee duly executed by, the Holder thereof or his attorney
duly authorized in writing), and the Company shall execute, and the Trustee
shall authenticate and deliver to the Holder of such Collateral Bond, without
service charge, a new Collateral Bond of any authorized denomination as
requested by such Holder and of like tenor and in aggregate principal amount
equal to and in exchange for the portion of the principal of the Collateral Bond
so surrendered that is not being repurchased.

     

    Section
2.04     [Reserved].

    

    Section
2.05     Restrictions on
Transfer.  The Collateral Bonds shall be issued to and
registered in the name of the Administrative Agent and shall not be transferable
by the Administrative Agent, except to (i) a successor Administrative Agent
appointed pursuant to the terms of Section 10.06 of the Credit Agreement or (ii)
the Company.  The Company hereby instructs the Trustee to so limit
transfers requested by any Holder (other than the Company) of any Collateral
Bond.

    

    Section
2.06     Sinking
Fund.  The Collateral Bonds are not subject to any sinking
fund.

     

       
Section 2.07      Surrender.  The
Administrative Agent shall surrender the Collateral Bonds to the Trustee when
all of the Borrower Obligations shall have been duly paid in full in immediately
available funds, and the Credit Agreement (including, without limitation, all
Commitments thereunder) shall have been terminated, and the Trustee shall cancel
such Collateral Bonds upon receipt thereof.

    TEXAS-NEW

    [FORM OF REVERSE OF FIRST
MORTGAGE BOND, DUE 2014, SERIES 2009B]

     

    This
Security 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 and
delivered 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 Second
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, 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, 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 called and held as provided in the
Indenture, and 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 “First Mortgage Bonds,
due 2014, Series 2009B” (herein called the “Collateral Bonds”) of
the Company, issued under and secured by the Indenture and described in an
indenture supplemental thereto (herein called the “Second Supplemental
Indenture”), dated as of March 25, 2009, executed by the Company and
delivered to the Trustee.

     

    The
Collateral Bonds are to be issued and delivered to the Administrative Agent as
collateral security for the Borrower Obligations and Related Hedging
Obligations.

     

    The
obligation of the Company to make payments with respect to the principal of the
Collateral Bonds shall be fully or partially, as the case may be, satisfied and
discharged to the extent that, at the time that any such payment shall be due,
the portion of the Borrower Obligations constituting then due principal under
the Credit Agreement shall have been fully or partially paid or pre-paid in
immediately available funds.  Satisfaction of any obligation to the
extent that payment or pre-payment is made with respect to the Borrower
Obligations means that if any payment or pre-payment is made on the principal of
the Borrower Obligations under the Credit Agreement, a corresponding payment
obligation with respect to the principal of the 

     

    
      
        
          A-4

        

      

      
        
        

        
          

        

      

      
        
        

      

    

    Collateral
Bonds shall be deemed discharged in the same amount as the payment or
pre-payment with respect to the Borrower Obligations discharges the outstanding
obligation with respect to such Borrower Obligations.  Such full or
partial payment or pre-payment of principal of the Borrower Obligations shall
automatically reduce the aggregate principal amount of the Collateral Bonds,
provided that,
if at the time of such full or partial payment or pre-payment all amounts then
due in respect of the Related Hedging Obligations shall have not been paid in
full in immediately available funds, such automatic reduction of the aggregate
principal amount of the Collateral Bonds shall not be deemed to have occurred
until such time, if any, that the Company has paid or pre-paid all amounts then
due in respect of the Related Hedging Obligations.

     

    The
obligation of the Company to make payments with respect to interest on the
Collateral Bonds shall be fully or partially, as the case may be, satisfied and
discharged to the extent that, at the time that any such payment shall be due,
the portion of the Borrower Obligations constituting then due interest and/or
fees under the Credit Agreement shall have been fully or partially
paid.  Satisfaction of any obligation to the extent that payment is
made with respect to the interest and/or fees under the Credit Agreement means
that if any payment is made on the interest and/or fees then comprising a
portion of the Borrower Obligations under the Credit Agreement, a corresponding
payment obligation with respect to the interest on the Collateral Bonds shall be
deemed discharged in the same amount as the payment with respect to the interest
and/or fees then comprising a portion of the Borrower Obligations under the
Credit Agreement discharges the outstanding obligation under the Credit
Agreement with respect to such interest and/or fees.

    

    The
Trustee may at any time and all times conclusively presume that (i) the
obligation of the Company to make payments with respect to the principal of and
interest on the Collateral Bonds, so far as such payments at the time have
become due, has been fully satisfied and discharged unless and until a
Responsible Officer of the Trustee shall have received at the Corporate Trust
Office a written notice from the Administrative Agent stating (A) that
timely payment of principal and interest on the Collateral Bonds has not been
made, (B) that the Company is in arrears as to the payments required to be
made by it to the Administrative Agent pursuant to the Credit Agreement and
(C) the amount of the arrearage; and (ii) no Credit Repurchase Requirement
or Hedge Repurchase Requirement shall exist in respect of any Credit Repurchase
Date or Hedge Repurchase Date, as the case may be, unless and until a
Responsible Officer of the Trustee shall have received at the Corporate Trust
Office a copy of a Credit Notice or a Credit Written Demand or a copy of a Hedge
Notice or a Hedge Written Demand in respect of such Credit Repurchase
Requirement or Hedge Purchase Requirement, as the case may be.  This
paragraph is solely for the benefit of the Trustee.

    

    This
Collateral Bond is not redeemable at the option of the Company.

     

    On a
Credit Repurchase Date, the Company shall repurchase (the “Credit Repurchase
Requirement”) an aggregate principal amount of the Collateral Bonds equal
to the lesser of, as of the applicable Credit Repurchase Date, (A) the Borrower
Obligations and (B) the Available Principal Amount (the “Credit Repurchase
Amount”).  On the Credit Repurchase Date, the Company will
deposit with the Trustee immediately available funds in an amount equal to the
Credit Repurchase Amount and the Trustee shall pay such amount as soon as
practicable after receipt thereof to the Administrative Agent upon surrender by
the Administrative Agent to the 

     

    
      
        
          A-5

        

      

      
        
        

        
          

        

      

      
        
        

      

    

    Trustee
at the Corporate Trust Office of the Trustee of Collateral Bonds in an aggregate
principal amount equal to the Credit Repurchase Amount, which surrender shall be
a condition to the Company’s Credit Repurchase Requirement.

     

    Payment
of a Credit Repurchase Amount equal to the Borrower Obligations as of the
applicable Credit Repurchase Date shall be deemed to satisfy and discharge
principal of, and accrued and unpaid interest on, the Collateral Bonds in the
same amount as the amount of principal and accrued and unpaid interest,
respectively, comprising such Borrower Obligations.  Such satisfaction
and discharge shall automatically reduce the aggregate principal amount of the
Collateral Bonds by the aggregate amount of such Borrower Obligations comprising
principal.

     

    Payment
of a Credit Repurchase Amount equal to the Available Principal Amount plus
accrued and unpaid interest on the Available Principal Amount, in each case, as
of the applicable Credit Repurchase Date shall be deemed to satisfy and
discharge all outstanding principal of and accrued and unpaid interest on the
Collateral Bonds as of such Credit Repurchase Date.

     

    On a
Hedge Repurchase Date, the Company shall repurchase (the “Hedge Repurchase
Requirement”) an aggregate principal amount of the Collateral Bonds equal
to the lesser of, as of the applicable Hedge Repurchase Date, (A) the Settlement
Amount and (B) the Available Principal Amount (the “Hedge Repurchase
Amount”).  On the Hedge Repurchase Date, the Company will
deposit with the Trustee immediately available funds in an amount equal to the
Hedge Repurchase Amount and the Trustee shall pay such amount as soon as
practicable after receipt thereof to the Administrative Agent upon surrender by
the Administrative Agent to the Trustee at the Corporate Trust Office of the
Trustee of Collateral Bonds in an aggregate principal amount equal to the Hedge
Repurchase Amount, which surrender shall be a condition to the Company’s Hedge
Repurchase Requirement.

     

    The
Company’s obligation to satisfy a Credit Repurchase Requirement or Hedge
Repurchase Requirement shall be mandatory upon, respectively, the occurrence of
a Credit Repurchase Event or a Hedge Repurchase Event.  Upon a Credit
Acceleration Event or a Hedge Acceleration Event, the Administrative Agent may,
at its option, deliver a Credit Written Demand or a Hedge Written Demand,
respectively, upon the Company’s receipt of which the Company’s compliance with
the Credit Repurchase Requirement or Hedge Repurchase Requirement, as
applicable, shall be mandatory.

     

    Any
Collateral Bond which is to be repurchased only in part shall be surrendered at
a Place of Payment therefor (with, if the Company or the Trustee so requires,
due endorsement by, or a written instrument of transfer in form satisfactory to
the Company and the Trustee duly executed by, the Holder thereof or his attorney
duly authorized in writing), and the Company shall execute, and the Trustee
shall authenticate and deliver to the Holder of such Collateral Bond, without
service charge, a new Collateral Bond of any authorized denomination as
requested by such Holder and of like tenor and in aggregate principal amount
equal to and in exchange for the portion of the principal of the Collateral Bond
so surrendered that is not being repurchased.

     

    In case
an Event of Default shall occur, the principal of all the Collateral Bonds at
any such time outstanding under the Indenture may be declared or may become due
and payable, 

     

    
      
        
          A-6

        

      

      
        
        

        
          

        

      

      
        
        

      

    

    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 Collateral Bonds
outstanding.

    

    Except as
set forth in Section 2.05 of the Second Supplemental Indenture, this Collateral
Bond is not transferable by the Holder thereof.

    

    No
recourse shall be had for the payment of the principal of, or the interest on,
this Collateral 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 Collateral Bond
and as part of the consideration for the issue hereof, and being likewise
released by the terms of the Indenture.

    

    This
Collateral Bond shall be governed by, and construed in accordance with, the laws
of the State of New York (including without limitation Section 5-1401 of the New
York General Obligations Law or any successor to such statute), except to the
extent that the Trust Indenture Act would be applicable were the Second
Supplemental Indenture qualified under the Trust Indenture Act and except to the
extent that the law of any other jurisdiction shall mandatorily govern the
creation, perfection, priority or enforcement of the Lien of the Indenture or
the exercise of remedies with respect to the Mortgaged Property.

    

    The
Administrative Agent shall surrender this Collateral Bond to the Trustee when
all of the Borrower Obligations shall have been duly paid in full in immediately
available funds, and the Credit Agreement (including, without limitation, all
Commitments thereunder) shall have been terminated, and the Trustee shall cancel
such Collateral Bonds upon receipt thereof.

    

    All
capitalized terms used but not defined in this Collateral Bond shall have the
meanings assigned to them in the Indenture or the Second Supplemental Indenture,
as applicable.
