	 	(27)	any provisions relating to the deferral of payment of any interest; and 

  

	 	(28)	any other terms not inconsistent with this Indenture. 

  
 All Securities of one series need not be issued at the same time and, unless otherwise provided, a series may be reopened for issuances of additional
Securities of such series. 
  
 The creation and issuance of a
series and the authentication and delivery thereof are not subject to any conditions precedent. 
  
 SECTION 2.02 Execution and Authentication. 
  
 Two Officers shall sign the Securities by manual or facsimile signature. The Company’s seal shall be reproduced on the Securities, which seal may be
affixed or in facsimile form. An Officer shall sign any coupons by facsimile signature. 
  
 If an Officer whose signature is on a Security or its coupons no longer holds that office at the time the Security is authenticated or delivered, the Security and coupons shall nevertheless be valid. 
  
 A Security and its coupons shall not be valid until the Security is
authenticated by the manual signature of the Registrar. The signature shall be conclusive evidence that the Security has been authenticated under this Indenture. 
  
 Each Registered Security shall be dated the date of its authentication. Each Bearer Security shall be dated the date of its
authentication or as provided in the Securities Resolution. 
  
 Securities may have notations, legends or endorsements required by law, stock exchange rule, agreement or usage, which shall be provided to the Trustee in writing by the Company. 
  

 5 








 In the event Securities are issued in electronic or other uncertificated form, such Securities may be
validly issued without the signatures or seal contemplated by this Section 2.02. 
  
 SECTION 2.03 Securities Agents. 
  
 The Company shall maintain an office or agency where Securities may be authenticated (“Registrar”), where Securities may be presented for
registration of transfer or for exchange (“Transfer Agent”) and where Securities may be presented for payment (“Paying Agent”). Whenever the Company must issue or deliver Securities pursuant to this Indenture, the Registrar shall
authenticate the Securities at the Company’s request. The Transfer Agent shall keep a register of the Securities and of their transfer and exchange. 
  
 The Trustee shall be, and is hereby appointed as, the Registrar. The Company may appoint more than one Transfer Agent or Paying Agent for a series. The
Company shall notify the Trustee of the name and address of any Agent not a party to this Indenture. If the Company fails to maintain a Transfer Agent or Paying Agent for a series, the Trustee shall act as such. 
  
 SECTION 2.04 Bearer Securities. 
  
 U.S. laws and Treasury Regulations restrict sales or exchanges of and
payments on Bearer Securities. Therefore, except as provided below: 
  

	 	(1)	Bearer Securities will be offered, sold and delivered only outside the United States and will be delivered only upon presentation of a certificate in a form prescribed by the
Company to comply with U.S. laws and regulations. 

  

	 	(2)	Bearer Securities will not be issued in exchange for Registered Securities. 

  

	 	(3)	All payments of principal and interest (including original issue discount) on Bearer Securities will be made outside the United States by a Paying Agent located outside the United
States unless the Company determines that: 

  

	 	(A)	such payments may not be made by such Paying Agent because the payments are illegal or prevented by exchange controls as described in Treasury Regulation section 1.163-5(c)(2)(v);
and 

  

	 	(B)	making the payments in the United States would not have an adverse tax effect on the Company. 

  
 If there is a change in the relevant provisions of U.S. laws or Treasury Regulations or the judicial or administrative
interpretation thereof, a restriction set forth in paragraph (1), (2) or (3) above will not apply to a series if the Company determines that the relevant provisions no longer apply to the series or that failure to comply with the relevant provisions
would not have an adverse tax effect on the Company or on Securityholders or cause the series to be treated as “registration-required” obligations under U.S. law. 
  
 The Company shall notify the Trustee in writing of any determinations by the Company under this Section. 
  

 6 








 “Treasury Regulations” means regulations of the U.S. Treasury Department under the Internal
Revenue Code of 1986, as amended. 
  
 SECTION
2.05 Paying Agent to Hold Money in Trust. 
  
 The Company shall
require each Paying Agent for a series other than the Trustee to agree in writing that the Paying Agent will hold in trust for the benefit of the persons entitled thereto all money held by the Paying Agent for the payment of principal of or interest
on the series, and will notify the Trustee in writing of any default by the Company in making any such payment. 
  
 While any such default continues, the Trustee may require a Paying Agent to pay all money so held by it to the Trustee. The Company at any time may
require a Paying Agent to pay all money held by it to the Trustee. Upon payment over to the Trustee, the Paying Agent shall have no further liability for the money. 
  
 If the Company or an Affiliate acts as Paying Agent for a series, it shall segregate and hold as a separate trust fund all
money held by it as Paying Agent for the series. 
  
 SECTION 2.06 Securityholder Lists. 
  
 The Trustee shall
preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of Securityholders. If the Trustee is not the Transfer Agent, the Company shall furnish to the Trustee semiannually and at
such other times as the Trustee may request a list in such form and as of such date as the Trustee may reasonably require of the names and addresses of Holders of Registered Securities and Holders of Bearer Securities whose names are on the list
referred to below. 
  
 The Transfer Agent shall keep a list of the
names and addresses of Holders of Bearer Securities who file a request to be included on such list. A request will remain in effect for two years but successive requests may be made. 
  
 Whenever the Company or the Trustee is required to mail a notice to all Holders of Registered Securities of a series, it
also shall mail the notice to Holders of Bearer Securities of the series whose names are on the list, if any. 
  
 Whenever the Company is required to publish a notice to all Holders of Bearer Securities of a series, it also shall mail the notice to such of them whose
names are on the list, if any. 
  
 SECTION 2.07
Transfer and Exchange. 
  
 Where Registered Securities of a
series are presented to the Transfer Agent with a request to register a transfer or to exchange them for an equal principal amount of Registered Securities of other denominations of the series, the Transfer Agent shall register the transfer or make
the exchange if its requirements for such transactions are met. Where Bearer Securities of a series are presented to the Transfer Agent with a request to exchange them for an equal principal amount of Bearer Securities of other denominations of the
series, the Transfer Agent shall make the exchange if its requirements for such transactions are met. 
  

 7 








 The Transfer Agent may require a Holder to pay a sum sufficient to cover any taxes imposed on a transfer
or exchange. 
  
 If a series provides for Registered and Bearer
Securities and for their exchange, Bearer Securities may be exchanged for Registered Securities and Registered Securities may be exchanged for Bearer Securities as provided in the Securities or the Securities Resolution establishing the series if
the requirements of the Transfer Agent for such transactions are met and if Section 2.04 permits the exchange. 
  
 SECTION 2.08 Replacement Securities. 
  
 If the Holder of a Security or coupon claims that it has been lost, destroyed or wrongfully taken, then, in the absence of notice to the Company or the
Trustee that the Security or coupon has been acquired by a bona fide purchaser, the Company shall issue a replacement Security or coupon if the Company and the Trustee receive: 
  

	 	(1)	evidence satisfactory to them of the loss, destruction or taking; 

  

	 	(2)	an indemnity bond satisfactory to them; and 

  

	 	(3)	payment of a sum sufficient to cover their expenses and any taxes for replacing the Security or coupon. 

  
 A replacement Security shall have coupons attached corresponding to those, if any, on the replaced Security. 
  
 Every replacement Security or coupon is an additional obligation of the
Company. 
  
 SECTION 2.09 Outstanding Securities.

  
 The Securities outstanding at any time are all the Securities
authenticated by the Registrar except for those canceled by it, those delivered to it for cancellation, and those described in this Section as not outstanding. 
  

If a Security is replaced pursuant to Section 2.08, it ceases to be outstanding unless the Trustee and the Company receive proof satisfactory to them
that the replaced Security is held by a bona fide purchaser. 
  
 If Securities are considered paid under Section 4.01, they cease to be outstanding and interest on them ceases to accrue. 
  
 A Security does not cease to be outstanding because the Company or an Affiliate holds the Security. 
  
 SECTION 2.10 Discounted Securities. 
  
 In determining whether the Holders of the required principal amount of
Securities have concurred in any direction, waiver or consent, the principal amount of a Discounted Security shall be the amount of principal that would be due as of the date of such determination if payment of the Security were accelerated on that
date. 
  

 8 








 SECTION 2.11 Treasury Securities. 
  
 In determining whether the Holders of the required principal amount of
Securities have concurred in any direction, waiver or consent, Securities owned by the Company or an Affiliate shall be disregarded, except that for the purposes of determining whether the Trustee shall be protected in relying on any such direction,
waiver or consent, only Securities for which the Trustee has received an Officers’ Certificate stating that such Securities are so owned shall be so disregarded. 
  
 SECTION 2.12 Global Securities. 
  
 If the Securities Resolution establishing a series so provides, the Company may issue some or all of the Securities of the
series in temporary or permanent global form. A global Security may be in registered form, in bearer form with or without coupons or in uncertificated form. A global Security shall represent that amount of Securities of a series as specified in the
global Security or as endorsed thereon from time to time. At the Company’s request, the Registrar shall endorse a global Security to reflect the amount of any increase or decrease in the Securities represented thereby. 
  
 The Company may issue a global Security only to a depositary designated by
the Company. A depositary may transfer a global Security only as a whole to its nominee or to a successor depositary. 
  
 The Securities Resolution may establish, among other things, the manner of paying principal and interest on a global Security and whether and upon what
terms a beneficial owner of an interest in a global Security may exchange such interest for definitive Securities. 
  
 The Company, an Affiliate, the Trustee and any Agent shall not be responsible for any acts or omissions of a depositary, for any depositary records of
beneficial ownership interests or for any transactions between the depositary and beneficial owners. 
  
 SECTION 2.13 Temporary Securities. 
  
 Until definitive Securities of a series are ready for delivery, the Company may use temporary Securities. Temporary Securities shall be substantially in
the form of definitive Securities but may have variations that the Company considers appropriate for temporary Securities. Temporary Securities may be in global form. Temporary Bearer Securities may have one or more coupons or no coupons. Without
unreasonable delay, the Company shall deliver definitive Securities in exchange for temporary Securities. 
  
 SECTION 2.14 Cancellation. 
  
 The Company at any time may deliver Securities to the Registrar for cancellation. The Transfer Agent and the Paying Agent shall forward to the Registrar
any Securities and coupons surrendered to them for payment, exchange or registration of transfer. The Registrar shall cancel 

  

 9 








 
all Securities or coupons surrendered for payment, registration of transfer, exchange or cancellation as follows: the Registrar will cancel all Registered
Securities and matured coupons. The Registrar also will cancel all Bearer Securities and unmatured coupons unless the Company requests the Registrar to hold the same for redelivery. Any Bearer Securities so held shall be considered delivered for
cancellation under Section 2.09. The Registrar shall destroy canceled Securities and coupons and deliver a certificate of cancellation thereof to the Company unless the Company otherwise directs. 
  
 Unless the Securities Resolution establishing a series otherwise provides,
the Company may not issue new Securities to replace Securities that the Company has paid or that the Company has delivered to the Registrar for cancellation. 
  
 SECTION 2.15 Defaulted Interest. 
  
 If the Company defaults in a payment of interest on Registered Securities, it need not pay the defaulted interest to Holders on the regular record date.
The Company may fix a special record date for determining Holders entitled to receive defaulted interest or the Company may pay defaulted interest in any other lawful manner. 
  
 ARTICLE 3 - REDEMPTION 
  
 SECTION 3.01 Notices to Trustee. 
  
 Securities of a series that are redeemable before maturity shall be redeemable in accordance with their terms and, unless the Securities Resolution
establishing the series otherwise provides, in accordance with this Article. 
  
 In the case of a redemption by the Company, the Company shall notify the Trustee of the redemption date and the principal amount of Securities to be redeemed. The Company shall notify the Trustee at least 35 days
before the redemption date unless a shorter notice is satisfactory to the Trustee. 
  
 If the Company is required to redeem Securities, it may reduce the principal amount of Securities required to be redeemed to the extent it is permitted a credit by the terms of the Securities and it notifies the
Trustee of the amount of the credit and the basis for it. If the reduction is based on a credit for acquired or redeemed Securities that the Company has not previously delivered to the Registrar for cancellation, the Company shall deliver the
Securities at the same time as the notice. 
  
 SECTION 3.02 Selection of Securities to Be Redeemed. 
  
 If less than all the Securities of a series are to be redeemed, the Trustee shall select the Securities to be redeemed pro rata or by any other method the Trustee considers fair and appropriate, unless the Company otherwise directs in
writing. The Trustee shall make the selection from Securities of the series outstanding not previously called for redemption. The Trustee may select for redemption portions of the principal of Securities having denominations 

  

 10 








 
larger than the minimum denomination for the series. Securities and portions thereof selected for redemption shall be in amounts equal to the minimum
denomination for the series or an integral multiple thereof. Provisions of this Indenture that apply to Securities called for redemption also apply to portions of Securities called for redemption. 
  
 SECTION 3.03 Notice of Redemption. 
  
 At least 30 days but not more than 60 days before a redemption date, or
within such other period as may be specified in the Securities Resolution creating the series of Securities to be redeemed, the Company shall mail a notice of redemption by first-class mail to each Holder of Registered Securities whose Securities
are to be redeemed. 
  
 If Bearer Securities are to be redeemed,
the Company shall publish a notice of redemption in an Authorized Newspaper as provided in the Securities. 
  
 A notice shall identify the Securities of the series to be redeemed and shall state: 
  

	 	(1)	the redemption date; 

  

	 	(2)	the redemption price; 

  

	 	(3)	the name and address of the Paying Agent; 

  

	 	(4)	that Securities called for redemption, together with all coupons, if any, maturing after the redemption date, must be surrendered to the Paying Agent to collect the redemption
price; 

  

	 	(5)	that interest on Securities called for redemption ceases to accrue on and after the redemption date; 

  

	 	(6)	whether the redemption by the Company is mandatory or optional; and 

  

	 	(7)	whether the redemption is conditional as provided in Section 3.04, the terms of the condition, and that, if the condition is not satisfied or is not waived by the Company, the
Securities will not be redeemed and such a failure to redeem will not constitute an Event of Default. 

  
 A redemption notice given by publication need not identify Registered Securities to be redeemed. 
  
 At the Company’s request, the Trustee shall give the notice of
redemption in the Company’s name and at its expense. 
  
 SECTION 3.04 Effect of Notice of Redemption. 
  
 Except as provided below, once notice of redemption is given, Securities called for redemption become due and payable on the redemption date at the redemption price stated in the notice. 
  

 11 








 A notice of redemption may provide that it is subject to the occurrence of any event before the date
fixed for such redemption as described in such notice (“Conditional Redemption”) and such notice of Conditional Redemption shall be of no effect unless all such conditions to the redemption have occurred on or before such date or have been
waived by the Company. 
  
 SECTION 3.05 Payment
of Redemption Price. 
  
 On or before the redemption date, the
Company shall deposit with the Paying Agent money sufficient to pay the redemption price of and accrued interest on all Securities to be redeemed on that date. 
  

When the Holder of a Security surrenders it for redemption in accordance with the redemption notice, the Company shall pay to the Holder on the
redemption date the redemption price and accrued interest to such date, except that: 
  

	 	(1)	the Company will pay any such interest (except defaulted interest) to Holders on the record date of Registered Securities if the redemption date occurs on an interest payment date;
and 

  

	 	(2)	the Company will pay any such interest to Holders of coupons that mature on or before the redemption date upon surrender of such coupons to the Paying Agent.


  
 Coupons maturing after the redemption date on a
called Security are void absent a payment default on that date. Nevertheless, if a Holder surrenders for redemption a Bearer Security missing any such coupons, the Company may deduct the face amount of such coupons from the redemption price. If
thereafter the Holder surrenders to the Paying Agent the missing coupons, the Company will return the amount so deducted. The Company also may waive surrender of the missing coupons if it receives an indemnity bond satisfactory to the Company.

  
 SECTION 3.06 Securities Redeemed in Part.

  
 Upon surrender of a Security that is redeemed in part, the
Company shall deliver to the Holder a new Security of the same series equal in principal amount to the unredeemed portion of the Security surrendered. 
  
 ARTICLE 4 - COVENANTS 
  
 SECTION 4.01 Payment of Securities. 
  
 The Company shall pay the principal of and interest on a series in accordance with the terms of the Securities for the series, any related coupons, and
this Indenture. On each payment date, the Company shall have deposited with the Paying Agent in funds which are then immediately available money sufficient to pay all principal and interest then due on the series. Principal and interest on a series
shall be considered paid on the date due if the Paying Agent for the series holds on that date money sufficient to pay all principal and interest then due on the series. 
  

 17 








 SECTION 4.02 Overdue Interest. 
  
 Unless the Securities Resolution establishing a series otherwise provides,
the Company shall pay interest on overdue principal of a Security of a series at the rate (or Yield to Maturity in the case of a Discounted Security) borne by the series; it shall pay interest on overdue installments of interest at the same rate or
Yield to Maturity to the extent lawful. 
  
 SECTION 4.03 No Lien Created, etc. 
  
 This Indenture
and the Securities do not create a Lien, charge or encumbrance on any property of the Company or any Subsidiary. 
  
 SECTION 4.04 Compliance Certificate. 
  
 The Company shall deliver to the Trustee, within 120 days after the end of each fiscal year of the Company, a brief certificate signed by the principal
executive officer, principal financial officer or principal accounting officer of the Company, as to the signer’s knowledge of the Company’s compliance with all conditions and covenants under this Indenture (determined without regard to
any period of grace or requirement of notice provided herein). 
  
 Any other obligor on the Securities also shall deliver to the Trustee such a certificate similarly signed as to its compliance with this Indenture within 120 days after the end of each of its fiscal years. 
  
 The certificates need not comply with Section 10.04. 
  
 SECTION 4.05 SEC Reports. 
  
 The Company shall provide to the Trustee, within 15 days after the Company
is required to file the same with the SEC, copies of the annual reports and of the information, documents, and other reports (or such portions of the foregoing as the SEC may prescribe) which the Company is required to file with the SEC pursuant to
Section 13 or 15(d) of the Securities Exchange Act of 1934.

 SECTION 4.07 Limitations on Liens. 
  
 So long as there remain outstanding any Securities of any series to which
this Section 4.07 applies under the terms of the series, the Company will not, and will not permit any Subsidiary to, create or suffer to be created or to exist any Lien on any of its properties or assets now owned or hereafter acquired to secure
any indebtedness, without making effective provision whereby the Securities of such series shall be equally and ratably secured with any and all such indebtedness and with any other indebtedness similarly entitled to be equally and ratably secured.
However, this restriction shall not apply to or prevent the creation or existence of: 
  

	 	(1)	Liens on property existing at the time of acquisition or construction of such property (or created within one year after completion of such acquisition or construction), whether by
purchase, merger, construction or otherwise (or on the property of a Subsidiary at the date it became a Subsidiary), or to secure the payment of all or any part of the purchase price or construction cost thereof, including the extension of any such
Liens to repairs, renewals, replacements, substitutions, betterments, additions, extensions and improvements then or thereafter made on the property subject thereto;

course of business. 
  
 ARTICLE 5 - SUCCESSORS 
  
 SECTION 5.01 When Company May Merge, etc. 
  
 Unless the Securities Resolution establishing a series otherwise provides,
the Company shall not consolidate with or merge into any Person in any transaction in which the Company is not the survivor, or transfer all or substantially all of its property to any Person, unless: 
  

	 	(1)	the Person is organized under the laws of the United States or a State thereof; 

  

	 	(2)	the Person assumes by supplemental indenture all the obligations of the Company under this Indenture, the Securities and any coupons; 

  

	 	(3)	all required approvals of any regulatory body having jurisdiction over the transaction shall have been obtained;

	 	(4)	immediately after the transaction no Default exists; and 

  

	 	(5)	the Company provides an Officers’ Certificate and an Opinion of Counsel to the effect that all the provisions in this Section 5.01 have been complied with.


  
 The successor shall be substituted for the
Company, and thereafter all obligations of the Company under this Indenture, the Securities and any coupons shall terminate. 
  
 ARTICLE 6 - DEFAULTS AND REMEDIES 
  
 SECTION 6.01 Events of Default. 
  
 Unless the Securities Resolution establishing a series otherwise provides, an “Event of Default” on the series so established occurs if:

  

	 	(1)	the Company defaults in any payment of interest on any Securities of the series when the same becomes due and payable and the Default continues for a period of 60 days;


  

	 	(2)	the Company defaults in the payment of the principal of any Securities of the series when the same becomes due and payable at maturity or upon redemption, acceleration or otherwise;


  

	 	(3)	the Company defaults in the payment or satisfaction of any sinking fund obligation with respect to any Securities of the series as required by the Securities Resolution establishing
such series and the Default continues for a period of 60 days; 

  

	 	(4)	the Company defaults in the performance of any of its other agreements applicable to the series and the Default continues for 90 days after the notice specified below;


  

	 	(5)	the Company pursuant to or within the meaning of any Bankruptcy Law: 

  

	 	(A)	commences a voluntary case, 

  

	 	(B)	consents to the entry of an order for relief against it in an involuntary case, 

  

	 	(C)	consents to the appointment of a Custodian for it or for all or substantially all of its property, or 

  

	 	(D)	makes a general assignment for the benefit of its creditors; 

  

	 	(6)	a court of competent jurisdiction enters an order or decree under any Bankruptcy Law that: 

  

	 	(A)	is for relief against the Company in an involuntary case, 

  

 17 









	 	(B)	appoints a Custodian for the Company or for all or substantially all of its property, or 

  

	 	(C)	orders the liquidation of the Company, 

  
 and the order or decree remains unstayed and in effect for 60 days; or 
  

	 	(7)	there occurs any other Event of Default provided for in the series. 

  
 The term “Bankruptcy Law” means Title 11, U.S. Code or any similar Federal or State law for the relief of debtors. The term
“Custodian” means any receiver, trustee, assignee, liquidator or a similar official under any Bankruptcy Law. 
  
 A Default under clause (4) is not an Event of Default until the Trustee or the Holders of at least 25% in principal amount of the series notify the
Company of the Default and the Company does not cure the Default within the time specified after receipt of the notice. The notice must specify the Default, demand that it be remedied and state that the notice is a “Notice of Default.” If
Holders notify the Company of a Default, they shall notify the Trustee at the same time. 
  
 Unless the Securities Resolution establishing a series provides otherwise, a Default on a series of Securities issued under this Indenture does not constitute a Default on any other series of Securities issued under
this Indenture. 
  
 The failure to redeem any Security subject to
a Conditional Redemption is not an Event of Default if any event on which such redemption is so conditioned does not occur and is not waived before the scheduled redemption date. 
  
 SECTION 6.02 Acceleration. 
  
 If an Event of Default occurs and is continuing on a series, the Trustee by notice to the Company, or the Holders of at
least 25% in principal amount of the series by notice to the Company and the Trustee, may declare the principal of and accrued interest on all the Securities of the series to be due and payable immediately. Discounted Securities may provide that the
amount of principal due upon acceleration is less than the stated principal amount. 
  
 The Holders of a majority in principal amount of the series by notice to the Trustee may rescind an acceleration and its consequences if the rescission would not conflict with any judgment or decree and if all
existing Events of Default on the series have been cured or waived except nonpayment of principal or interest that has become due solely because of the acceleration. 
  
 SECTION 6.03 Other Remedies. 
  
 If an Event of Default occurs and is continuing on a series, the Trustee may pursue any available remedy to collect
principal or interest then due on the series, to enforce the performance of any provision applicable to the series, or otherwise to protect the rights of the Trustee and Holders of the series. 
  

 18 








 The Trustee may maintain a proceeding even if it does not possess any of the Securities or coupons or
does not produce any of them in the proceeding. A delay or omission by the Trustee or any Securityholder in exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy or constitute a waiver of or
acquiescence in the Event of Default. All remedies are cumulative to the extent permitted by law. 
  
 SECTION 6.04 Waiver of Past Defaults. 
  
 The Holders of a majority in principal amount of a series by notice to the Trustee may waive an existing Default on the series and its consequences
except: 
  

	 	(1)	a Default in the payment of the principal of or interest on the series, or 

  

	 	(2)	a Default in respect of a provision that under Section 9.02 cannot be amended without the consent of each Securityholder affected. 

  
 SECTION 6.05 Control by Majority. 
  
 The Holders of a majority in principal amount of a series may direct the
time, method and place of conducting any proceeding for any remedy available to the Trustee, or of exercising any trust or power conferred on the Trustee, with respect to the series. However, the Trustee may refuse to follow any direction that
conflicts with law or this Indenture. 
  
 SECTION
6.06 Limitation on Suits. 
  
 A Securityholder of a series may
pursue a remedy with respect to the series only if: 
  

	 	(1)	the Holder gives to the Trustee notice of a continuing Event of Default on the series; 

  

	 	(2)	the Holders of at least 25% in principal amount of the series make a request to the Trustee to pursue the remedy; 

  

	 	(3)	such Holder or Holders offer to the Trustee indemnity satisfactory to the Trustee against any loss, liability or expense; 

  

	 	(4)	the Trustee does not comply with the request within 60 days after receipt of the request and the offer of indemnity; and 

  

	 	(5)	during such 60-day period the Holders of a majority in principal amount of the series do not give the Trustee a direction inconsistent with such request. 


 
 A Securityholder may not use this Indenture to prejudice the rights of
another Securityholder or to obtain a preference or priority over another Securityholder. 
  
 SECTION 6.07 Collection Suit by Trustee. 
  
 If an Event of Default in payment of interest, principal or sinking fund obligation specified in Section 6.01(1), (2) or (3) occurs and is continuing on a
series, the Trustee may recover judgment in its own name and as trustee of an express trust against the Company for the whole amount of principal and interest remaining unpaid on the series. 
  

 19 








 SECTION 6.08 Priorities. 
  
 If the Trustee collects any money for a series pursuant to this Article, it shall pay out the money in the following order:

  
 First: to the Trustee for amounts due under Section 7.06;

  
 Second: to Securityholders of the series for amounts due and
unpaid for principal and interest, ratably, without preference or priority of any kind, according to the amounts due and payable for principal and interest, respectively; and 
  
 Third: to the Company. 
  
 The Trustee may fix a payment date for any payment to Securityholders. 
  
 ARTICLE 7 - TRUSTEE 
  
 SECTION 7.01 Rights of Trustee. 
  

	 	(1)	The Trustee may rely on any document believed by it to be genuine and to have been signed or presented by the proper person. The Trustee need not investigate any fact or matter
stated in the document. 

  

	 	(2)	Before the Trustee acts or refrains from acting, it may require an Officers’ Certificate or an Opinion of Counsel. The Trustee shall not be liable for any action it takes or
omits to take in good faith in reliance on the Certificate or Opinion. 

  

	 	(3)	The Trustee may act through agents and shall not be responsible for the misconduct or negligence of any agent appointed with due care. 

  

	 	(4)	The Trustee shall not be liable for any action it takes or omits to take in good faith in accordance with a direction received by it pursuant to Section 6.05.


  

	 	(5)	The Trustee may refuse to perform any duty or exercise any right or power which it reasonably believes may expose it to any loss, liability or expense unless it receives indemnity
satisfactory to it against such loss, liability or expense. 

  

	 	(6)	The Trustee shall not be liable for interest on any money received by it except as the Trustee may agree with the Company. Money held in trust by the Trustee need not be segregated
from other funds except to the extent required by law. 

  

	 	(7)	The Trustee shall have no duty with respect to a Default unless a Trust Officer has received written notice of such Default. 

  

 20 









	 	(8)	The Trustee shall not be liable for any action it takes or omits to take in good faith which it believes to be authorized and within its powers. 

  

	 	(9)	Any Agent shall have the same rights and be protected to the same extent as if it were Trustee. 

  
 SECTION 7.02 Individual Rights of Trustee. 
  
 The Trustee in its individual or any other capacity may become the owner or pledgee of Securities or coupons and may
otherwise deal with the Company or an Affiliate with the same rights it would have if it were not Trustee. Any Agent may do the same with like rights. 
  
 SECTION 7.03 Trustee’s Disclaimer. 
  
 The Trustee makes no representation as to the validity or adequacy of this Indenture or the Securities or any coupons; it shall not be accountable for the
Company’s use of the proceeds from the Securities; it shall not be responsible for any statement in the Securities or any coupons; it shall not be responsible for any overissue; it shall not be responsible for determining whether the form and
terms of any Securities or coupons were established in conformity with this Indenture; and it shall not be responsible for determining whether any Securities were issued in accordance with this Indenture. 
  
 SECTION 7.04 Notice of Defaults. 
  
 If a Default occurs and is continuing on a series and if it is known to the
Trustee, the Trustee shall mail a notice of the Default within 90 days after it occurs to Holders of Registered Securities of the series. Except in the case of a Default in payment on a series, the Trustee may withhold the notice if and so long as a
committee of its Trust Officers in good faith determines that withholding the notice is in the interest of Holders of the series. The Trustee shall withhold notice of a Default described in Section 6.01(4) until at least 90 days after it occurs.

  
 SECTION 7.05 Reports by Trustee to Holders.

  
 Any report required by TIA Section 313(a) to be mailed to

listed on a stock exchange. 
  
 SECTION 7.06

 The Company shall pay to the
Trustee from time to time reasonable compensation for its services. The Trustee’s compensation shall not be limited by any law on compensation of a trustee of an express trust. The Company shall reimburse the Trustee upon request for all
reasonable out-of-pocket expenses incurred by it. Such expenses shall include the reasonable compensation and expenses of the Trustee’s agents and counsel. 
  


 21 








 The Company shall indemnify the Trustee (including its officers, directors and employees) against any
loss or liability incurred by it. The Trustee shall notify the Company promptly of any claim for which it may seek indemnity. The Company shall defend the claim and the Trustee shall cooperate in the defense. The Trustee may have separate counsel

 SECTION 7.07 Replacement of Trustee. 
  
 A resignation or removal of the Trustee and appointment of a successor Trustee shall become effective only upon the successor Trustee’s acceptance of
appointment as provided in this Section. 
  
 The Trustee may
resign by so notifying the Company. The Holders of a majority in principal amount of the Securities may remove the Trustee by so notifying the Trustee and may appoint a successor Trustee with the Company’s consent. 
  
 The Company may remove the Trustee if: 
  

	 	(1)	the Trustee fails to comply with TIA Section 310(a) or TIA Section 310(b) or with Section 7.09; 

  

	 	(2)	the Trustee is adjudged a bankrupt or an insolvent; 

  

	 	(3)	a Custodian or other public officer takes charge of the Trustee or its property; 

  

	 	(4)	the Trustee becomes incapable of acting; or 

  

	 	(5)	an event of the kind described in Section 6.01(5) or (6) occurs with respect to the Trustee. 

  

 22 








 The Company also may remove the Trustee with or without cause if the Company so notifies the Trustee
three months in advance and if no Default occurs or is continuing during the three-month period. 
  
 If the Trustee resigns or is removed or if a vacancy exists in the office of Trustee for any reason, the Company shall promptly appoint a successor
Trustee. 
  
 If a successor Trustee does not take office within 30
days after the retiring Trustee resigns or is removed, the retiring Trustee, the Company or the Holders of a majority in principal amount of the Securities may petition any court of competent jurisdiction for the appointment of a successor Trustee.

  
 If the Trustee fails to comply with TIA Section 310(a) or TIA
Section 310(b) or with Section 7.09, any Securityholder may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee.

 ARTICLE 8 - DISCHARGE OF
INDENTURE 
  
 SECTION 8.01 Defeasance.

  
 Securities of a series may be defeased in accordance with
their terms and, unless the Securities Resolution establishing the series otherwise provides, in accordance with this Article. 
  
 The Company at any time may terminate as to a series all of its obligations under this Indenture, the Securities of a series and any related coupons
(“legal defeasance option”). The Company at any time may terminate as to a series its obligations, if any, under Section 4.07 and any other restrictive covenants which may be applicable to a particular series (“covenant defeasance
option”). However, in the case of the legal defeasance option, the Company’s 

  

 23 








 
obligations in Sections 2.03, 2.04, 2.05, 2.06, 2.07, 2.08, 7.06, 7.07 and 8.04 shall survive until the Securities of the series are no longer outstanding;
thereafter the Company’s obligations in Section 7.06 shall survive. 
  
 The Company may exercise its legal defeasance option notwithstanding its prior exercise of its covenant defeasance option. If the Company exercises its legal defeasance option, a series may not be accelerated because
of an Event of Default. If the Company exercises its covenant defeasance option, a series may not be accelerated by reference to Section 4.07 or any other restrictive covenants which may be applicable to a particular series so defeased under the
terms of the series. 
  
 The Trustee upon request shall
acknowledge in writing the discharge of those obligations that the Company terminates. 
  
 SECTION 8.02 Conditions to Defeasance. 
  
 The Company may exercise as to a series its legal defeasance option or its covenant defeasance option if: 
  

	 	(1)	the Company irrevocably deposits in trust with the Trustee or another trustee money or U.S. Government Obligations; 

  

	 	(2)	the Company delivers to the Trustee a certificate from a nationally recognized firm of independent accountants expressing their opinion that the payments of principal and interest
when due on the deposited U.S. Government Obligations without reinvestment plus any deposited money without investment will provide cash at such times and in such amounts as will be sufficient to pay principal and interest when due on all the
Securities of the series to maturity or redemption, as the case may be; 

  

	 	(3)	immediately after the deposit no Default exists; 

  

	 	(4)	the deposit does not constitute a default under any other agreement binding on the Company; 

  

	 	(5)	the deposit does not cause the Trustee to have a conflicting interest under TIA Section 310(a) or TIA Section 310(b) as to another series; 

  

	 	(6)	the Company delivers to the Trustee an Opinion of Counsel to the effect that Holders of the series will not recognize income, gain or loss for Federal income tax purposes as a
result of the defeasance; and 

  

	 	(7)	91 days pass after the deposit is made and during the 91-day period no Default specified in Section 6.01(5) or (6) occurs that is continuing at the end of the period.


  
 Before or after a deposit the Company may make
arrangements satisfactory to the Trustee for the redemption of Securities at a future date in accordance with Article 3. 
  

 24 








 “U.S. Government Obligations” means securities which are direct obligations of (i) the United
States or (ii) an agency or instrumentality of the United States, the payment of which is unconditionally guaranteed by the United States, which, in either case, have the full faith and credit of the United States pledged for payment and are not
callable at the issuer’s option, or certificates representing an ownership interest in such obligations. 
  
 SECTION 8.03 Application of Trust Money. 
  
 The Trustee shall hold in trust money or U.S. Government Obligations deposited with it pursuant to Section 8.02. It shall apply the deposited money and
the money from U.S. Government Obligations through the Paying Agent and in accordance with this Indenture to the payment of principal and interest on Securities of the defeased series. 
  
 SECTION 8.04 Repayment to Company. 
  
 The Trustee and the Paying Agent shall promptly turn over to the Company upon request any excess money or securities held by
them at any time. 
  
 The Trustee and the Paying Agent shall pay
to the Company upon request any money held by them for the payment of principal or interest that remains unclaimed for two years. After payment to the Company, Securityholders entitled to the money must look to the Company for payment as unsecured
general creditors unless an abandoned property law designates another person. 
  
 ARTICLE 9 - AMENDMENTS AND WAIVERS 
  
 SECTION 9.01 Without Consent of Holders. 
  
 The Company and the Trustee may amend this Indenture, the Securities or any coupons without the consent of any Securityholder: 
  

	 	(1)	to cure any ambiguity, omission, defect or inconsistency; 

  

	 	(2)	to comply with Article 5; 

  

	 	(3)	to provide that specific provisions of this Indenture shall not apply to a series not previously issued; 

  

	 	(4)	to create a series and establish its terms; 

  

	 	(5)	to provide for a separate Trustee for one or more series; or 

  

	 	(6)	to make any change that does not materially adversely affect the rights of any Securityholder. 

  

 25 








 SECTION 9.02 With Consent of Holders. 
  
 The Company and the Trustee may amend this Indenture, the Securities or any
coupons with the written consent of the Holders of a majority in principal amount of the Securities of all series affected by the amendment voting as one class. However, without the consent of each Securityholder affected, an amendment under this
Section may not: 
  

	 	(1)	reduce the amount of Securities whose Holders must consent to an amendment; 

  

	 	(2)	reduce the interest on or change the time for payment of interest on any Security; 

  

	 	(3)	change the fixed maturity of any Security; 

  

	 	(4)	reduce the principal of any non-Discounted Security or reduce the amount of principal of any Discounted Security that would be due upon an acceleration thereof;


  

	 	(5)	change the currency in which principal or interest on a Security is payable; or 

  

	 	(6)	make any change in Section 6.04 or 9.02, except to increase the amount of Securities whose Holders must consent to an amendment or waiver or to provide that other provisions of this
Indenture cannot be amended or waived without the consent of each Securityholder affected thereby. 

  
 An amendment of a provision included solely for the benefit of one or more series does not affect Securityholders of any other series. 
  
 Securityholders need not consent to the exact text of a proposed amendment or
waiver; it is sufficient if they consent to the substance thereof. 
  
 SECTION 9.03 Compliance with Trust Indenture Act. 
  
 Every amendment pursuant to Section 9.01 or 9.02 shall be set forth in a supplemental indenture that complies with the TIA as then in effect. 
  
 If a provision of the TIA requires or permits a provision of this Indenture and the TIA provision is amended, then the
Indenture provision shall be automatically amended to like effect. 
  
 SECTION 9.04 Effect of Consents. 
  
 An amendment or waiver becomes effective in accordance with its terms and thereafter binds every Securityholder entitled to consent to it. 
  
 A consent to an amendment or waiver by a Holder of a Security is a continuing consent by the Holder and every subsequent Holder of a Security that
evidences the same debt as the consenting Holder’s Security. Any Holder or subsequent Holder may revoke the consent as to his Security if the Trustee receives notice of the revocation before the amendment or waiver becomes effective.

  

 26 








 The Company may fix a record date for the determination of Holders of Registered Securities entitled to
give a consent. The record date shall not be less than 10 nor more than 60 days prior to the first written solicitation of Securityholders. 
  
 SECTION 9.05 Notation on or Exchange of Securities. 
  
 The Company or the Trustee may place an appropriate notation about an amendment or waiver on any Security thereafter
authenticated. The Company may issue in exchange for affected Securities new Securities that reflect the amendment or waiver. 
  
 SECTION 9.06 Trustee Protected. 
  
 The Trustee need not sign any supplemental indenture that adversely affects its rights. The Trustee shall be entitled to receive, and shall be fully
protected in relying upon, an Opinion of Counsel and an Officers’ Certificate each stating that the execution of any amendment or supplement or waiver authorized pursuant to this Article is authorized or permitted by this Indenture, and that
such amendment or supplement or waiver constitutes the legal, valid and binding obligation of the Company. 
  
 ARTICLE 10 - MISCELLANEOUS 
  
 SECTION 10.01 Trust Indenture Act. 
  
 The provisions of TIA Sections 310 through 317 that impose duties on any person (including the provisions automatically deemed included herein unless
expressly excluded by this Indenture) are a part of and govern this Indenture, whether or not expressly set forth herein. 
  
 If any provision of this Indenture limits, qualifies or conflicts with another provision which is required to be included in this Indenture by the TIA,
the required provision shall control.

                     of each year commencing
                    , 20    . Interest on the Securities will accrue from the most recent date to which interest

 The Company will pay interest on the Securities to the persons who are registered holders of Securities at the close of business on the record date for
the next interest payment date, except as otherwise provided in the Indenture. Holders must surrender Securities to a Paying Agent to collect principal payments. The Company will pay principal and interest in money of the United States that at the
time of payment is legal tender for payment of public and private debts. The Company may pay principal and interest by check payable in such money. It may mail an interest check to a holder’s registered address. 
  

	3.	Securities Agents.(2A) 

  
 Initially, U.S. Bank National Association will act as Paying Agent, Transfer Agent and Registrar. The Company may change any Paying Agent or Transfer

	4.	Indenture. 

  
 The Company issued the securities of this series (the “Securities”) under an Indenture dated as of December 1, 2003 (the “Indenture”) between the Company and U.S. Bank National Association (the

                     thereafter through
                     at a redemption price of 100% of principal amount, plus accrued interest to the redemption date.(5) The Company may
reduce the principal amount of Securities to be redeemed pursuant to this paragraph by subtracting 100% of the principal amount (excluding premium) of any Securities (i) that the Company has acquired or that the Company has redeemed other than
pursuant to this paragraph and (ii) that the Company has delivered to the Registrar for cancellation. The Company may so subtract the same Security only once. 
  

	7.	Additional Optional Redemption.(6) 

  
 In addition to redemptions pursuant to the above paragraph(s), the Company may redeem not more than
$             principal amount of Securities on                      and on

interest to the redemption date. 
  

	8.	Notice of Redemption.(7) 

  
 Notice of redemption will be mailed at least [30 days but not more than 60 days] before the redemption date to each holder of Securities to be redeemed at
such holder’s registered address. 
  
 A notice of redemption
may provide that it is subject to the occurrence of any event before the date fixed for such redemption as described in such notice (“Conditional Redemption”) and such notice of Conditional Redemption shall be of no effect unless all such
conditions to the redemption have occurred before such date or have been waived by the Company. 
  

	9.	Denominations, Transfer, Exchange. 

  
 The Securities are in registered form without coupons in denominations of $1,000(8) and whole multiples of $1,000. The transfer of Securities may be
registered and Securities may be exchanged as provided in the Indenture. The Transfer Agent may require a 
  

 A-3 








 
holder, among other things, to furnish appropriate endorsements and transfer documents and to pay any taxes and fees required by law or the Indenture. The
Transfer Agent need not exchange or register the transfer of any Security or portion of a Security selected for redemption. Also, it need not exchange or register the transfer of any Securities for a period of 15 days before a selection of
Securities to be redeemed. 
  

	10.	Persons Deemed Owners. 

  
 The registered holder of a Security may be treated as its owner for all purposes. 
  

	11.	Amendments and Waivers. 

  
 Subject to certain exceptions, the Indenture or the Securities may be amended with the consent of the holders of a majority in principal amount of the
securities of all series affected by the amendment.(9) 
  
 Subject to certain exceptions, a default on a series may be waived with the consent of the holders of a majority in principal amount of the series. 
  
 Without the consent of any Securityholder, the Indenture or the Securities may be amended, among other things, to cure any ambiguity, omission, defect or
inconsistency; to provide for assumption of Company obligations to Securityholders; or to make any change that does not materially adversely affect the rights of any Securityholder. 
  

	12.	Restrictive Covenants.(10) 

  
 The Securities are unsecured general obligations of the Company [initially] limited to
$                     principal amount. [The Company may from time to time without notice to, or the consent of, the holders of the
Securities, create and issue further securities of the same series, equal in rank to the Securities in all respects (or in all respects except for the payment of interest accruing prior to the issue date of the new securities or except for the first
payment of interest following the issue date of the new securities) so that the new securities may be consolidated and form a single series with the Securities and have the same terms as to status, redemption or otherwise as the Securities.] The
Indenture does not limit other unsecured debt. Section 4.07 of the Indenture, which if applicable limits certain mortgages and other liens, [will] [will not] apply with respect to the Securities. [The limitations are subject to a number of important
qualifications and exceptions.] 
  

	13.	Successors. 

  
 When a successor assumes all the obligations of the Company under the Securities and the Indenture, the Company will be released from those obligations. 
  

	14.	Defeasance Prior to Redemption or Maturity.(11) 

  
 Subject to certain conditions, the Company at any time may terminate some or all of its obligations under the Securities and the Indenture if the Company
deposits with the Trustee money or U.S. Government Obligations for the payment of principal and interest 
  

 A-4 








 on the Securities to redemption or maturity. U.S. Government Obligations are securities backed by the
full faith and credit of the United States of America or certificates representing an ownership interest in such Obligations. 
  

	15.	Defaults and Remedies. 

  
 An Event of Default(12) includes: default for 60 days in payment of interest on the Securities; default in payment of principal on the Securities; default
for 60 days in the payment or satisfaction of any sinking fund obligation with respect to the Securities; default by the Company for a specified period after notice to it in the performance of any of its other agreements applicable to the
Securities; certain events of bankruptcy or insolvency; and any other Event of Default provided for in the series. If an Event of Default occurs and is continuing, the Trustee or the holders of at least 25% in principal amount of the Securities may
declare the principal(13) of all the Securities to be due and payable immediately. 
  
 Securityholders may not enforce the Indenture or the Securities except as provided in the Indenture. The Trustee may require indemnity satisfactory to it before it enforces the Indenture or the Securities. Subject to
certain limitations, holders of a majority in principal amount of the Securities may direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Securityholders notice of any continuing default (except a default in

the rate per annum shown above. The Company will pay interest semiannually on
                                        
and
                                        
of each year commencing                     , 20    . Interest on the Securities will accrue from the most recent
date to which interest has been paid or, if no interest has been paid, from                     , 20    . Interest
will be computed on the basis of a 360-day year of twelve 30-day months. 
  

	2.	Method of Payment.(2) 

  
 Holders must surrender Securities and any coupons to a Paying Agent to collect principal and interest payments. The Company will pay principal and
interest in money of the United States that at the time of payment is legal tender for payment of public and private debts. The Company may pay principal and interest by check payable in such money. 
  

	3.	Securities Agents.(2A) 

  
 Initially, U.S. Bank National Association will act as Transfer Agent, Paying Agent and Registrar. The Company may change any Paying Agent or Transfer
Agent without notice. The Company or any Affiliate may act in any such capacity. Subject to certain conditions, the Company may change the Trustee. 
  

	4.	Indenture. 

  
 The Company issued the securities of this series (the “Securities”) under an Indenture dated as of December 1, 2003 (the “Indenture”) between the Company and U.S. Bank National Association (the
“Trustee”). The terms of the Securities include those stated in the Indenture and the Securities Resolution establishing the series and those made part of the Indenture by the Trust Indenture Act of 1939 (15 U.S. Code Sections

	6.	Mandatory Redemption.(4) 

  
 The Company will redeem $             principal amount of Securities on
                     and on each
                     thereafter through
                     at a redemption price of 100% of principal amount, plus accrued interest to the redemption date(5). The Company may
reduce the principal amount of Securities to be redeemed pursuant to this paragraph by subtracting 100% of the principal amount (excluding premium) of any Securities (i) that the Company has acquired or that the Company has redeemed other than
pursuant to this paragraph and (ii) that the Company has delivered to the Registrar for cancellation. The Company may so subtract the same Security only once. 
  

	7.	Additional Optional Redemption.(6) 

  
 In addition to redemptions pursuant to the above paragraph(s), the Company may redeem not more than
$             principal amount of Securities on                      and on
each                      thereafter through
                     at a redemption price of 100% of principal amount, plus accrued interest to the redemption date. 
  

	8.	Notice of Redemption.(7) 

  
 Notice of redemption will be published once in an Authorized Newspaper in the City of New York and if the Securities are listed on any stock exchange
located outside the United States and such stock exchange so requires, in any other required city outside the United States at least [30 days but not more than 60 days] before the redemption date. Notice of redemption also will be mailed to holders
who have filed their names and addresses with the Transfer Agent within the two preceding years. Holders of Securities may miss important notices if they fail to maintain their names and addresses with the Transfer Agent. 
  
 A notice of redemption may provide that it is subject to the occurrence of
any event before the date fixed for such redemption as described in such notice (“Conditional Redemption”) and such notice of Conditional Redemption shall be of no effect unless all such conditions to the redemption have occurred before
such date or have been waived by the Company. 
  

 B-3 









	9.	Denominations, Transfer, Exchange. 

  
 The Securities are in bearer form with coupons in denominations of $5,000(8) and whole multiples of $5,000. The Securities may be transferred by delivery
and exchanged as provided in the Indenture. Upon an exchange, the Transfer Agent may require a holder, among other things, to furnish appropriate documents and to pay any taxes and fees required by law or the Indenture. The Transfer Agent need not
exchange any Security or portion of a Security selected for redemption. Also, it need not exchange any Securities for a period of 15 days before a selection of Securities to be redeemed. 
  

	10.	Persons Deemed Owners. 

  
 The holder of a Security or coupon may be treated as its owner for all purposes. 
  

	11.	Amendments and Waivers. 

  
 Subject to certain exceptions, the Indenture or the Securities may be amended with the consent of the holders of a majority in principal amount of the
securities of all series affected by the amendment.(9) 
  
 Subject to certain exceptions, a default on a series may be waived with the consent of the holders of a majority in principal amount of the series. 
  
 Without the consent of any Securityholder, the Indenture or the Securities may be amended, among other things, to cure any ambiguity, omission, defect or
inconsistency; to provide for assumption of Company obligations to Securityholders; or to make any change that does not materially adversely affect the rights of any Securityholder. 
  

	12.	Restrictive Covenants.(10) 

  
 The Securities are unsecured general obligations of the Company [initially] limited to
$             principal amount. [The Company may from time to time without notice to, or the consent of, the holders of the Securities, create and issue further securities of the
same series, equal in rank to the Securities in all respects (or in all respects except for the payment of interest accruing prior to the issue date of the new securities or except for the first payment of interest following the issue date of the
new securities) so that the new securities may be consolidated and form a single series with the Securities and have the same terms as to status, redemption or otherwise as the Securities.] The Indenture does not limit other unsecured debt. Section
4.07 of the Indenture, which if applicable limits certain mortgages and other liens, [will] [will not] apply with respect to the Securities. [The limitations are subject to a number of important qualifications and exceptions.] 
  

	13.	Successors. 

  
 When a successor assumes all the obligations of the Company under the Securities, any coupons and the Indenture, the Company will be released from those obligations. 
  

 B-4 









	14.	Defeasance Prior to Redemption or Maturity.(11) 

  
 Subject to certain conditions, the Company at any time may terminate some or all of its obligations under the Securities, any coupons and the Indenture if
the Company deposits with the Trustee money or U.S. Government Obligations for the payment of principal and interest on the Securities to redemption or maturity. U.S. Government Obligations are securities backed by the full faith and credit of the
United States of America or certificates representing an ownership interest in such Obligations. 
  

	15.	Defaults and Remedies. 

  
 An Event of Default(12) includes: default for 60 days in payment of interest on the Securities; default in payment of principal on the Securities; default
for 60 days in the payment or satisfaction of any sinking fund obligation with respect to the Securities; default by the Company for a specified period after notice to it in the performance of any of its other agreements applicable to the
Securities; certain events of bankruptcy or insolvency; and any other Event of Default provided for in the series. If an Event of Default occurs and is continuing, the Trustee or the holders of at least 25% in principal amount of the Securities may
declare the principal(13) of all the Securities to be due and payable immediately. 
  
 Securityholders may not enforce the Indenture or the Securities except as provided in the Indenture. The Trustee may require indemnity satisfactory to it before it enforces the Indenture or the Securities. Subject to
certain limitations, holders of a majority in principal amount of the Securities may direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Securityholders notice of any continuing default (except a default in
payment of principal or interest) if it determines that withholding notice is in their interests. The Company must furnish an annual compliance certificate to the Trustee. 
  

	16.	Trustee Dealings with Company. 

  
 U.S. Bank National Association, the Trustee under the Indenture, in its individual or any other capacity, may make loans to, accept deposits from, and
perform services for the Company or its Affiliates, and may otherwise deal with those persons, as if it were not Trustee. 
  

	17.	No Recourse Against Others. 

  
 A director, officer, employee or stockholder, as such, of the Company shall not have any liability for any obligations of the Company under the Securities
or the Indenture or for any claim based on, in respect of or by reason of such obligations or their creation. Each Securityholder by accepting a Security waives and releases all such liability. The waiver and release are part of the consideration
for the issue of the Securities. 
  

	18.	Authentication. 

  
 This Security shall not be valid until authenticated by a manual signature of the Registrar.

	19.	Abbreviations. 

  
 Customary abbreviations may be used in the name of a Securityholder or an assignee, such as: TEN COM (=tenants in common), TEN ENT (=tenants by the
entirety), JT TEN (=joint tenants with right of survivorship and not as tenants in common), CUST (=custodian), U/G/M/A (=Uniform Gifts to Minors Act), and U/T/M/A (=Uniform Transfers to Minors Act).

copy of the Indenture and the Securities Resolution[, which contains the text of this Security in larger type]. Requests may be made to: Corporate Secretary, Wisconsin Gas Company, 231 West Michigan Street, P.O. Box 2046, Milwaukee, WI 53201.
