Section 8.1 hereof) shall be fully protected in relying upon:

 (1) A Board Resolution authorizing such Company Order or Orders and, if the form
of Securities is established by a Board Resolution or a Company Order pursuant to a Board Resolution, a copy of such Board Resolution; 

(2) an Opinion of Counsel stating substantially the following subject to customary qualifications and exceptions:

pursuant to a Board Resolution, or in a supplemental indenture as permitted by Section 2.1 hereof, that such form has been established in conformity with this Indenture; 

(B) that the Indenture has been duly authorized, executed and delivered by the Company and constitutes a valid
and binding obligation of the Company, enforceable against the Company in accordance with its terms, except to the extent that enforcement thereof may be limited by applicable bankruptcy, insolvency, reorganization, moratorium or similar laws of
general application relating to or affecting the enforcement of creditors and the application of general principles of equity (regardless of whether enforcement is sought in a proceeding at law or in equity) and except as enforcement of provisions
of the Indenture may be limited by state laws affecting the remedies for the enforcement of the security provided for in the Indenture; 

(C) that the Indenture is qualified to the extent necessary under the TIA; 

(D) that such Securities have been duly authorized and executed by the Company, and when authenticated by the

enforcement thereof may be limited by applicable bankruptcy, insolvency, reorganization, moratorium or similar laws of general application relating to or affecting the enforcement of creditors and the application of general principles of equity

Indenture; 
 (E) that the issuance of the Securities will not result in any default under this Indenture, or

upon the authentication by the Trustee of the series of Securities, will not be in default under any of the terms or covenants contained in the Indenture, and (ii) all conditions that must be met by the Company to issue Securities under this
Indenture have been met. 
 (d) The Trustee shall have the right to decline to authenticate and deliver any Security: 

(1) if the issuance of such Securities pursuant to this Indenture will affect the Trustee’s own rights, duties or
immunities under the Securities and this Indenture or otherwise in a manner that is not reasonably acceptable to the Trustee; 

(2) if the Trustee, being advised by counsel, determines that such action may not lawfully be taken; or 

(3) if the Trustee in good faith by its Board of Directors, executive officers or a trust committee of directors and/or
responsible officers determines that such action would expose the Trustee to personal liability to Holders of any outstanding Securities. 

(e) No Security shall be entitled to any benefit under this Indenture or be valid or obligatory for any purpose unless there
appears on such Security a certificate of authentication substantially in the form provided for herein executed by the Trustee by the manual signature of an authorized officer, and such certificate upon any Security shall be conclusive evidence, and
the only evidence, that such Security has been duly authenticated and delivered hereunder and is entitled to the benefits of this Indenture. 

(f) If all Securities of a series are not to be authenticated and issued at one time, the Company shall not be required to
deliver the Company Order, Board Resolutions, Officers’ Certificate and Opinion of Counsel (including any such that would be otherwise required pursuant to Section 14.5 hereof) described in Section 2.5(c) hereof at or prior to the
authentication of each Security of such series, if such items are delivered at or prior to the time of authentication of the first Security of such series to be authenticated and issued. If all of the Securities of a series are not authenticated and
issued at one time, for each issuance of Securities after the initial issuance of Securities, the Company shall be required only to deliver to the Trustee the Security and a written request (executed by one of the Chairman, the President, any Vice
President, the Treasurer, or an Assistant Treasurer, and the Secretary or an Assistant Secretary of the Company) to the Trustee to authenticate such Security and to deliver such Security in accordance with the instructions specified by such request.
Any such request shall constitute a representation and warranty by the Company that the statements made in the Officers’ Certificate delivered to the Trustee prior to the authentication and issuance of the first Security of such series are true
and correct on the date thereof as if made on and as of the date thereof. 

  
 11 








 Section 2.6. Exchange And Registration Of Transfer Of Securities. 

(a) Subject to Section 2.13 hereof, Securities may be exchanged for one or more new Securities of any authorized
denominations and of a like aggregate principal amount, series and stated maturity and having the same terms and Original Issue Date or Dates. Securities to be exchanged shall be surrendered at any of the offices or agencies to be maintained
pursuant to Section 5.2 hereof, and the Trustee shall deliver in exchange therefor the Security or Securities which the Securityholder making the exchange shall be entitled to receive. 

(b) The Trustee shall keep, at one of said offices or agencies, a register or registers in which, subject to such reasonable
regulations as it may prescribe, the Trustee shall register or cause to be registered Securities and shall register or cause to be registered the transfer of Securities as in this Article II provided. Such register shall be in written form or in any
other form capable of being converted into written form within a reasonable time. At all reasonable times, such register shall be open for inspection by the Company. Upon due presentment for registration of transfer of any Security at any such
office or agency, the Company shall execute and the Trustee shall register, authenticate and deliver in the name of the transferee or transferees one or more new Securities of any authorized denominations and of a like aggregate principal amount,
series and stated maturity and having the same terms and Original Issue Date or Dates. 
 (c) All Securities presented for
registration or for exchange, redemption or payment shall be duly endorsed by, or be accompanied by a written instrument or instruments of transfer in form satisfactory to the Company and the Trustee and duly executed by the Holder or the attorney
in fact of such Holder duly authorized in writing. 
 (d) No service charge shall be made for any exchange or registration of
transfer of Securities, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection therewith. 

(e) The Trustee shall not be required to exchange or register a transfer of any Securities selected, called or being called for
redemption (including Securities, if any, redeemable at the option of the Holder provided such Securities are then redeemable at such Holder’s option) except, in the case of any Security to be redeemed in part, the portion thereof not to be so
redeemed. 
 (f) If the principal amount, and applicable premium, of part, but not all of a Global Security is paid, then
upon surrender to the Trustee of such Global Security, the Company shall execute, and the Trustee shall authenticate, deliver and register, a Global Security in an authorized denomination in aggregate principal amount equal to, and having the same
terms, Original Issue Date or Dates and series as, the unpaid portion of such Global Security. 
 Section 2.7. Mutilated, Destroyed, Lost Or Stolen
Securities. 
 (a) If any temporary or definitive Security shall become mutilated or be destroyed, lost or stolen, the
Company shall execute, and upon its request the Trustee shall authenticate and deliver, a new Security of like form and principal amount and having the same terms and Original Issue Date or Dates and bearing a number not contemporaneously
outstanding, in exchange and substitution for the mutilated Security, or in lieu of and in substitution for the Security so destroyed, lost or stolen. In every case the applicant for a substituted Security shall furnish to the Company, the Trustee
and any paying agent or Authenticating Agent such security or indemnity 

  
 12 








 
as may be required by them to save each of them harmless, and, in every case of destruction, loss or theft of a Security, the applicant shall also furnish to the Company and to the Trustee
evidence to their satisfaction of the destruction, loss or theft of such Security and of the ownership thereof. 
 (b) The
Trustee shall authenticate any such substituted Security and deliver the same upon the written request or authorization of any officer of the Company. Upon the issuance of any substituted Security, the Company may require the payment of a sum
sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses connected therewith. If any Security which has matured, is about to mature, has been redeemed or called for redemption shall
become mutilated or be destroyed, lost or stolen, the Company may, instead of issuing a substituted Security, pay or authorize the payment of the same (without surrender thereof except in the case of a mutilated Security) if the applicant for such
payment shall furnish to the Company, the Trustee and any paying agent or Authenticating Agent such security or indemnity as may be required by them to save each of them harmless and, in case of destruction, loss or theft, evidence satisfactory to
the Company and the Trustee of the destruction, loss or theft of such Security and of the ownership thereof. 
 (c) Every
substituted Security issued pursuant to this Section 2.7 by virtue of the fact that any Security is mutilated, destroyed, lost or stolen shall constitute an additional contractual obligation of the Company, whether or not such destroyed, lost
or stolen Security shall be found at any time, and shall be entitled to all the benefits of this Indenture equally and proportionately with any and all other Securities duly issued hereunder. All Securities shall be held and owned upon the express
condition that, to the extent permitted by law, the foregoing provisions are exclusive with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities and shall preclude any and all other rights or remedies
notwithstanding any law or statute existing or hereafter enacted to the contrary with respect to the replacement or payment of negotiable instruments or other securities without their surrender. 

Section 2.8. Temporary Securities. Pending the preparation of definitive Securities, the Company may execute and the
Trustee shall authenticate and deliver temporary Securities (printed, lithographed or otherwise reproduced). Temporary Securities shall be issuable in any authorized denomination and substantially in the form of the definitive Securities but with
such omissions, insertions and variations as may be appropriate for temporary Securities, all as may be determined by the Company. Every such temporary Security shall be authenticated by the Trustee upon the same conditions and in substantially the
same manner, and with the same effect, as the definitive Securities. Without unreasonable delay the Company shall execute and shall deliver to the Trustee definitive Securities and thereupon any or all temporary Securities shall be surrendered in
exchange therefor at the corporate trust office of the Trustee, and the Trustee shall authenticate, deliver and register in exchange for such temporary Securities an equal aggregate principal amount of definitive Securities. Such exchange shall be
made by the Company at its own expense and without any charge therefor to the Securityholders. Until so exchanged, the temporary Securities shall be in the principal amount of definitive Securities. Such exchange shall be made by the Company at its
own expense and without any charge therefor to the Securityholders. Until so exchanges, the temporary Securities shall in all respects be entitled to the same benefits under this Indenture as definitive Securities authenticated and delivered
hereunder. 

  
 13 








 Section 2.9. Cancellation Of Securities Paid, Etc. All Securities
surrendered for the purpose of payment, redemption, exchange or registration of transfer shall be surrendered to the Trustee for cancellation and promptly canceled by it and no Securities shall be issued in lieu thereof except as expressly permitted
by this Indenture. The Company’s acquisition of any Securities shall operate as a redemption or satisfaction of the indebtedness represented by such Securities and such Securities shall be surrendered by the Company to and canceled by the
Trustee. 
 Section 2.10. Interest Rights Preserved. Each Security delivered under this Indenture upon transfer of
or in exchange for or in lieu of any other Security shall carry all the rights to interest accrued and unpaid, and to accrue, which were carried by such other Security, and each such Security shall be so dated that neither gain nor loss of interest
shall result from such transfer, exchange or substitution. 
 Section 2.11. Special Record Date. If and to the
extent that the Company fails to make timely payment or provision for timely payment of interest on any series of Securities (other than on an Interest Payment Date that is a maturity date), that interest shall cease to be payable to the Persons who
were the Securityholders of such series at the applicable Regular Record Date. In that event, when moneys become available for payment of the interest, the Trustee shall (a) establish a date of payment of such interest and a Special Record Date
for the payment of that interest, which Special Record Date shall be not more than 15 or fewer than 10 days prior to the date of the proposed payment and (b) mail notice of the date of payment and of the Special Record Date not fewer than 10
days preceding the Special Record Date to each Securityholder of such series at the close of business on the 15th day preceding the mailing at the address of such Securityholder, as it appeared on the register for the Securities. On the day so
established by the Trustee the interest shall be payable to the Holders of the applicable Securities at the close of business on the Special Record Date. 

Section 2.12. Payment Of Securities. Payment of the principal, interest and premium on all Securities shall be
payable as follows: 
 (a) On or before 11:30 a.m., New York City time, of the day on which payment of principal, interest
and premium is due on any Global Security pursuant to the terms thereof, the Company shall deliver to the Trustee funds available on such date sufficient to make such payment, by wire transfer of immediately available funds or by instructing the
Trustee to withdraw sufficient funds from an account maintained by the Company with the Trustee or such other method as is acceptable to the Trustee and the Depository. On or before Noon, New York City time, or such other time as shall be agreed
upon between the Trustee and the Depository, of the day on which any payment of interest is due on any Global Security (other than at maturity) and following receipt of the necessary funds from the Company, the Trustee shall pay to the Depository
such interest in same day funds. On or before Noon, New York City time or such other time as shall be agreed upon between the Trustee and the Depository, of the day on which principal, interest payable at maturity and premium, if any, is due on any
Global Security and following receipt of the necessary funds from the Company, the Trustee shall deposit with the Depository the amount equal to 

  
 14 








 
the principal, interest payable at maturity and premium, if any, by wire transfer into the account specified by the Depository. As a condition to the payment, at maturity or upon redemption, of
any part of the principal of, interest on and applicable premium of any Global Security, the Depository shall surrender, or cause to be surrendered, such Global Security to the Trustee, whereupon a new Global Security shall be issued to the
Depository pursuant to Section 2.6(f) hereof. 
 (b) With respect to any Security that is not a Global Security,
principal, applicable premium and interest due at the maturity of the Security shall be payable in immediately available funds when due upon presentation and surrender of such Security at the corporate trust office of the Trustee or at the
authorized office of any paying agent. Interest on any Security that is not a Global Security (other than interest payable at maturity) shall be paid to the Holder thereof as its name appears on the register by check payable in clearinghouse funds;
provided that if the Trustee receives a written request from any Holder of Securities, ·the aggregate principal amount of which having the same Interest Payment Date equals or exceeds $10,000,000, on or before the applicable Regular Record
Date for such Interest Payment Date, interest shall be paid by wire transfer of immediately available funds to a bank within the continental United States designated by such Holder in its request or by direct deposit into the account of such Holder
designated by such Holder in its request if such account is maintained with the Trustee or any paying agent. 
 Section 2.13. Securities Issuable In
The Form Of A Global Security. 
 (a) If the Company shall establish pursuant to Section 2.5 hereof that the
Securities of a particular series are to be issued in whole or in part in the form of one or more Global Securities, then the Company shall execute and the Trustee shall, in accordance with Section 2.5 hereof and the Company Order delivered to
the Trustee thereunder, authenticate and deliver such Global Security or Securities, which (i) shall represent, shall be denominated in an amount equal to the aggregate principal amount of, and shall have the same terms as, the outstanding
Securities of such series to be represented by such Global Security or Securities, (ii) shall be registered in the name of the Depository or its nominee, (iii) shall be delivered by the Trustee to the Depository or pursuant to the
Depository’s instruction and (iv) shall bear a legend substantially to the following effect: “This Security is a Global Security registered in the name of the Depository (referred to herein) or a nominee thereof and, unless and until
it is exchanged in whole or in part for the individual Securities represented hereby, this Global Security may not be transferred except as a whole 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. Unless this Global Security is presented by an authorized representative of The Depository Trust
Company (55 Water Street, New York, New York), to the trustee for registration of transfer, exchange or payment, and any certificate issued is registered in the name of Cede & Co. or such other name as requested by an authorized
representative of The Depository Trust Company and 

  
 15 








 
any payment is made to Cede & Co., any transfer, pledge or other use hereof for value or otherwise by or to any person is wrongful since the registered owner hereof, Cede & Co.,
has an interest herein” or such other legend as may be required by the rules and regulations of the Depository. 
 (b)
Notwithstanding any other provision of Section 2.6 hereof or of this Section 2.13, unless the terms of a Global Security expressly permit such Global Security to be exchanged in whole or in part for individual Securities, a Global Security
may be transferred, in whole but not in part, only as described in the legend thereto. 
 (c) (i) If at any time the
Depository for a Global Security notifies the Company that it is unwilling or unable to continue as Depository for such Global Security or if at any time the Depository for the Global Security shall no longer be eligible or in good standing under
the Securities Exchange Act of 1934, as amended, or other applicable statute or regulation, the Company shall appoint a successor Depository with respect to such Global Security. If a successor Depository for such Global Security is not appointed by
the Company within 90 days after the Company receives such notice or becomes aware of such ineligibility, the Company’s election pursuant to Section 2.5(c)(vi) hereof shall no longer be effective with respect to the series of Securities
evidenced by such Global Security and the Company shall execute, and the Trustee, upon receipt of a Company Order for the authentication and delivery of individual Securities of such series in exchange for such Global Security, shall authenticate
and deliver, individual Securities of such series of like tenor and terms in definitive form in an aggregate principal amount equal to the principal amount of the Global Security in exchange for such Global Security. The Trustee shall not be charged
with knowledge or notice of the ineligibility of a Depository unless a responsible officer assigned to and working in its corporate trustee administration department shall have actual knowledge thereof. 

(ii) The Company may at any time and in its sole discretion determine that all outstanding (but not less than all) Securities
of a series issued or issuable in the form of one or more Global Securities shall no longer be represented by such Global Security or Securities. In such event the Company shall execute, and the Trustee, upon receipt of a Company Order for the
authentication and delivery of individual Securities in exchange for such Global Security, shall authenticate and deliver individual Securities of like tenor and terms in definitive form in an aggregate principal amount equal to the principal amount
of such Global Security or Securities in exchange for such Global Security or Securities. 
 (iii) In any exchange provided
for in any of the preceding two paragraphs, the Company will execute and the Trustee will authenticate and deliver individual Securities in definitive registered form in authorized denominations. Upon the exchange of a Global Security for individual
Securities, such Global Security shall be canceled by the Trustee. Securities issued in exchange for a Global Security pursuant to this Section shall be registered in such names and in such authorized denominations as the Depository for such Global
Security, pursuant to instructions from its direct or indirect participants or otherwise, shall instruct the Trustee. The Trustee shall deliver such Securities to the Depository for delivery to the persons in whose names such Securities are so
registered, or if the Depository shall refuse or be unable to deliver such 

  
 16 








 
Securities, the Trustee shall deliver such Securities to the persons in whose names such Securities are registered, unless otherwise agreed upon between the Trustee and the Company, in which
event the Company shall cause the Securities to be delivered to the persons in whose names such Securities are registered. 

(d) Neither the Company, the Trustee, any Authenticating Agent nor any paying agent shall have any responsibility or liability
for any aspect of the records relating to, or payments made on account of, beneficial ownership interests of a Global Security or for maintaining, supervising or reviewing any records relating to such beneficial ownership interest. 

(e) Pursuant to the provisions of this subsection, at the option of the Trustee and upon 30 days’ written notice to the
Depository but not prior to the first Interest Payment Date of the respective Global Securities, the Depository shall be required to surrender any two or more Global Securities which have identical terms, including, ·without limitation,
identical maturities, interest rates and redemption provisions (but which may have differing Original Issue Dates) to the Trustee, and the Company shall execute and the Trustee shall authenticate and deliver to, or at the direction of, the
Depository a Global Security in principal amount equal to the aggregate principal amount of, and with all terms identical to, the Global Securities surrendered thereto and that shall indicate each applicable Original Issue Date and the principal
amount applicable to each such Original Issue Date. The exchange contemplated in this subsection shall be consummated at least 30 days prior to any Interest Payment Date applicable to any of the Global Securities surrendered to the Trustee. Upon any
exchange of any Global Security with two or more Original Issue Dates, whether pursuant to this Section or pursuant to Section 2.6 or Section 3.3 hereof, the aggregate principal amount of the Securities with a particular Original Issue
Date shall be the same before and after such exchange, after giving effect to any retirement of Securities and the Original Issue Dates applicable to such Securities occurring in connection with such exchange. 

ARTICLE III. REDEMPTION OF SECURITIES 

Section 3.1. Applicability Of Article. Such of the Securities as are, by their terms, redeemable prior to
their stated maturity date at the option of the Company, may be redeemed by the Company at such times, in such amounts and at such prices as may be specified therein and in accordance with the provisions of this Article III. 

Section 3.2. Notice Of Redemption; Selection Of Securities. 

(a) The election of the Company to redeem any Securities shall be evidenced by a Board Resolution which shall be given with
notice of redemption to the Trustee at least 45 days (or such shorter period acceptable to the Trustee in its sole discretion) prior to the redemption date specified in such notice. 

  
 17 








 (b) Notice of redemption to each Holder of Securities to be redeemed as a whole
or in part shall be given by the Trustee, in the manner provided in Section 14.10 hereof, no less than 30 or more than 60 days prior to the date fixed for redemption. Any notice which is given in the manner herein provided shall be conclusively
presumed to have been duly given, whether or not the Securityholder receives the notice. In any case, failure duly to give such notice, or any defect in such notice, to the Holder of any Security designated for redemption as a whole or in part shall
not affect the validity of the proceedings for the redemption of any other Security. 
 (c) Each such notice shall specify
the date fixed for redemption, the places of redemption and the redemption price at which such Securities are to be redeemed, and shall state that payment of the redemption price of such Securities or portion thereof to be redeemed will be made upon
surrender of such Securities at such places of redemption, that interest accrued to the date fixed for redemption will be paid as specified in such notice, and that from and after such date interest thereon shall cease to accrue. If less than all of
a series of Securities having the same terms are to be redeemed, the notice shall specify the Securities or portions thereof to be redeemed. If any Security is to be redeemed in part only, the notice which relates to such Security shall state the
portion of the principal amount thereof to be redeemed, ·and shall state that, upon surrender of such Security, a new Security or Securities having the same terms in aggregate principal amount equal to the unredeemed portion thereof will be
issued. 
 (d) Unless otherwise provided by a supplemental indenture or Company Order under Section 2.5 hereof, if less
than all of a series of Securities is to be redeemed, the Trustee shall select in such manner as it shall deem appropriate and fair in its discretion the particular Securities to be redeemed in whole or in part and shall thereafter promptly notify
the Company in writing of the Securities so to be redeemed. If less than all of a series of Securities represented by a Global Security is to be redeemed, the particular Securities or portions thereof of such series to be redeemed shall be selected

principal amount of the Securities at the time outstanding; 
 (4) the entry of a decree or order by a court
having jurisdiction over the Company for relief in respect of the Company under Title 11 of the United States Code, as now constituted or hereafter amended, or any other applicable federal or state bankruptcy, insolvency or other similar law, or
appointing a receiver, liquidator, assignee, trustee, custodian, sequestrator or similar official of the Company or of any substantial part of its property, or ordering the winding-up or liquidation of its
affairs, and the continuance of any such decree or order unstayed and in effect for a period of 60 consecutive days; or 

(5) the filing by the Company with respect to itself or its property of a petition or answer or consent seeking
relief under Title 11 of the United States Code, as now constituted or hereafter amended, or any other applicable federal or state bankruptcy, insolvency or other similar law, or the consent by it to the institution of proceedings thereunder or to

then and in each and every such case, unless the principal of all of the Securities shall have already become due and payable, either the
Trustee or the Holders of a majority in aggregate principal amount of the Securities then outstanding, by notice in writing to the Company (and to the Trustee if given by Securityholders), may declare the principal of all the Securities to be due
and payable immediately and upon any such declaration the same shall become and shall be immediately due and payable, anything in this Indenture or in the Securities contained to the contrary notwithstanding. This provision, however, is subject to

the Company shall pay or shall deposit with the Trustee a sum sufficient to 

  
 27 








 pay all matured installments of interest upon all of the Securities and the principal of and any

and applicable premium at the rate borne by the Securities to the date of such payment or deposit) and all sums paid or advanced by the Trustee hereunder, the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel, and any other amounts due the Trustee under Section 8.6 hereof, and any and all defaults under this Indenture, other than the non-payment of principal of and accrued interest on Securities
which shall have become due solely by acceleration of maturity, shall have been cured or waived then and in every such case such payment or deposit shall cause an automatic waiver of the Event of Default and its consequences and shall cause an
automatic rescission and annulment of the acceleration of the Securities; but no such waiver or rescission and annulment shall extend to or shall affect any subsequent default, or shall impair any right consequent thereon. 

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

such further amounts as shall be sufficient to cover the costs and expenses of collection, including reasonable compensation to the Trustee, its agents, attorneys and counsel, any expenses or liabilities incurred by the Trustee hereunder other


  
 28 








 
than through its negligence or bad faith, and any other amounts due the Trustee under Section 8.6 hereof. 

(b) If the Company shall fail forthwith to pay such amounts upon such demand, the Trustee, in its own name and as trustee of an
express trust, shall be entitled and empowered to institute any actions or proceedings at law or in equity for the collection of the sums so due and unpaid, and may enforce any such judgment or final decree against the Company or any other obligor
on the Securities and collect in the manner provided by law out of the property of the Company or any other obligor on such series of Securities wherever situated, the moneys adjudged or decreed to be payable. 

(c) If there shall be pending proceedings for the bankruptcy or for the reorganization of the Company or any other obligor on
the Securities under the United States Bankruptcy Code or any other applicable law, or in case a receiver or trustee shall have been appointed for the property of the Company or such other obligor, or in the case of any similar judicial proceedings
relative to the Company or other obligor upon the Securities, or to the creditors or property of the Company or such other obligor, the Trustee, irrespective of whether the principal of the Securities shall then be due and payable as therein

claim or claims for the whole amount of principal and any premium and interest owing and unpaid in respect of the Securities, and, in case of any judicial proceedings, to file such proofs of claim and other papers or documents as may be necessary or
advisable in order to have the claims of the Trustee (including any amounts due to the Trustee under Section 8.6 hereof) and of the Holders of Securities allowed in such judicial proceedings relative to the Company or any other obligor on the
Securities, its or their creditors, or its or their property, and to collect and receive any moneys or other property payable or deliverable on any such claims, and to distribute the same after the deduction of its charges and expenses. 

(d) All claims and rights of action under this Indenture, or under any of the Securities, may be enforced by the Trustee
without the possession of any of the Securities, or the production thereof in any trial or other proceeding relative thereto, and any such suit or proceeding instituted by the Trustee shall be brought in its own name as trustee of an express trust,
and any recovery of judgment shall be for the ratable benefit of the Holders of the Securities in respect of which such action was taken. 

(e) Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent or to accept or adopt on behalf
of any Securityholder any plan of reorganization, arrangement, adjustment or composition affecting the Securities or the rights of any Holder thereof, or to authorize the Trustee to vote in respect of the claim of any Securityholder in any such
proceeding.

this Indenture to institute any suit, action or proceeding in equity or at law upon or under or with respect to this Indenture or for the appointment of a receiver or trustee, or for any other remedy hereunder, unless such Holder previously shall
have given to the Trustee written notice of an Event of Default with respect to such Security and of the continuance thereof, as hereinabove provided, and unless also Securityholders of a majority in aggregate principal amount of the Securities then
outstanding affected by such Event of Default shall have made 

  
 30 








 written request upon the Trustee to institute such action, suit or proceeding in its own name as
Trustee hereunder and shall have offered to the Trustee such reasonable indemnity as it may require against the costs, expenses and liabilities to be incurred therein or thereby, and the Trustee for 60 days after its receipt of such notice, request
and offer of indemnity, shall have neglected or refused to institute any such action, suit or proceeding. 
 (b)
Notwithstanding any other provision in this Indenture, however, the rights of any Holder of any Security to receive payment of the principal of and any premium and interest on such Security, on or after the respective due dates expressed in such
Security or on the applicable redemption date, or to institute suit for the enforcement of any such payment on or after such respective dates shall not be impaired or affected without the consent of such Holder. 

Section 7.5. Proceedings By Trustee. In case of an Event of Default hereunder the Trustee may in its discretion
proceed to protect and enforce the rights vested in it by this Indenture, by such appropriate judicial proceedings as the Trustee shall deem most effectual to protect and enforce any of such rights, either by suit in equity or by action at law or by
proceeding in bankruptcy or otherwise, whether for the specific enforcement of any covenant or agreement contained in this Indenture or in aid of the exercise of any power granted to it under this Indenture, or to enforce any other legal or
equitable right vested in the Trustee by this Indenture or by law. 
 Section 7.6. Remedies Cumulative And
Continuing. All powers and remedies given by this Article VII to the Trustee or to the Securityholders shall, to the extent permitted by law, be deemed cumulative and not exclusive of any powers and remedies hereof or of any other powers and
remedies available to the Trustee or the Holders of the Securities, by judicial proceedings or otherwise, to enforce the performance or observance of the covenants and agreements contained in this Indenture, and no delay or omission of the Trustee
or of any Holder of any of the Securities in exercising any right or power accruing upon any default occurring and continuing as aforesaid shall impair any such right or power, or shall be construed to be a waiver of any such default or an
acquiescence therein; and, subject to Section 7.4 hereof, every power and remedy given by this Article VII or by law to the Trustee or to the Securityholders may be exercised from time to time, and as often as shall be deemed expedient, by the
Trustee or by the Securityholders. 
 Section 7.7. Direction Of Proceedings And Waiver Of
Defaults By Majority Of Securityholders. The Holders of a majority in aggregate principal amount of the Securities at the time outstanding shall have the right to direct the time, method, and place of conducting any proceeding for
any remedy available to the Trustee, or exercising any trust or power conferred on the Trustee; provided, that (subject to Section 8.1 hereof) the Trustee shall have the right to decline to follow any such direction if the Trustee being advised
by counsel determines that the action or proceeding so directed may not lawfully be taken or if the Trustee in good faith by its board of directors or trustees, executive committee, or a trust committee of directors or trustees or responsible
officers shall determine that the action or proceeding so directed would involve the Trustee in personal liability or would be unduly prejudicial to the rights of Securityholders not joining in such directions. The Holders of a majority in aggregate
principal amount of the 

  
 31 








 
Securities at the time outstanding may on behalf of all of the Holders of the Securities waive any past default or Event of Default hereunder and its consequences except a default in the payment
of principal of or any premium or interest on the Securities. Upon any such waiver the Company, the Trustee and the Holders of the Securities shall be restored to their former positions and rights hereunder, respectively, but no such waiver shall
extend to any subsequent or other default or Event of Default or impair any right consequent thereon. Whenever any default or Event of Default hereunder shall have been waived as permitted by this Section 7.7, said default or Event of Default
shall for all purposes of the Securities and this Indenture be deemed to have been cured and to be not continuing. 

Section 7.8. Notice Of Default. The Trustee shall, within 90 days after the occurrence of a default, give to all
Holders of the Securities, in the manner provided in Section 14.10, notice of such default, unless such default shall have been cured before the giving of such notice, the term “default” for the purpose of this Section 7.8 being
hereby defined to be any event which is or after notice or lapse of time or both would become an Event of Default; provided that, except in the case of default in the payment of the principal of or any premium or interest on any of the Securities,
or in the payment of any sinking or purchase fund installments, the Trustee shall be protected in withholding such notice if and so long as its board of directors or trustees, executive committee, or a trust committee of directors or trustees or
responsible officers in good faith determines that the withholding of such notice is in the interests of the Holders of the Securities. The Trustee shall not be charged with knowledge of any Event of Default unless a responsible officer of the
Trustee assigned to the corporate trustee department of the Trustee shall have actual knowledge of such Event of Default. 

Section 7.9. Undertaking To Pay Costs. All parties to this Indenture agree, and each Holder of any Security by
acceptance thereof shall be deemed to have agreed, that any court may in its discretion require, in any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any action taken or omitted by it as
Trustee, the filing by any party litigant in such suit of an undertaking to pay the costs of such suit, and that such court may in its discretion assess reasonable costs, including reasonable attorneys’ fees, against any party litigant in such
suit, having due regard to the merits and good faith of the claims or defenses made by such party litigant; but this Section 7.9 shall not apply to any suit instituted by the Trustee, or to any suit instituted by any Securityholder, or group of
Securityholders, holding in the aggregate more than 10% in principal amount of the Securities outstanding, or to any suit instituted by any Securityholder for the enforcement of the payment of the principal of or any premium or interest on any
Security on or after the due date expressed in such Security or the applicable redemption date.

vested in it by this Indenture, and use the same degree of care and skill in their exercise, as a prudent man would exercise or use under the circumstances in the conduct of his own affairs. 

(b) No provisions of this Indenture shall be construed to relieve the Trustee from liability for its own negligent action, its
own negligent failure to act or its own willful misconduct, except that: 
 (1) prior to the occurrence of
any Event of Default and after the curing or waiving of all Events of Default which may have occurred 
 (A)
the duties and obligations of the Trustee shall be determined solely by the express provisions of this Indenture, and the Trustee shall not be liable except for the performance of such duties and obligations as are specifically set forth in this

any provision hereof are specifically required to be furnished to the Trustee, the Trustee shall be under a duty to examine the same to determine whether or not they conform to the requirements of this Indenture; 

(2) the Trustee shall not be liable for any error of judgment made in good faith by a responsible officer or
officers of the Trustee, unless it shall be proved that the Trustee was negligent in ascertaining the pertinent facts; and 

(3) the Trustee shall not be liable with respect to any action taken or omitted to be taken by it in good faith

request, order or direction of any of the Securityholders, pursuant to this Indenture, unless such Securityholders shall have offered to the Trustee reasonable security or indemnity against the costs, expenses and liabilities which may be incurred
by such exercise; 
 (e) the Trustee shall not be liable for any action taken, suffered or omitted by it in good faith and
believed by it to be authorized or within the discretion or rights or powers conferred upon it by this Indenture;

prior to the occurrence of an Event of Default hereunder and after the curing or waiving of all Events of Default, the Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement,
instrument, opinion, report, notice, request, consent, order, approval, note or other paper or document, unless requested in writing to do so by the Holders of at least a majority in principal amount of the then outstanding Securities; provided that
if the payment within a reasonable time to the Trustee of the costs, expenses or liabilities likely to be incurred by it in the making of such investigation is, in the opinion of the Trustee, not reasonably assured to the Trustee by the security
afforded to it by this Indenture, the Trustee may require reasonable indemnity against such expense or liability as a condition to so proceeding; 

(g) no provision of this Indenture shall require the Trustee to extend or risk its own funds or otherwise incur any financial

not reasonably assured to it; and 

  
 34 








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

Section 8.3. No Responsibility For Recitals, Etc. The recitals contained herein and in the Securities (except in the
certificate of authentication) shall be taken as the statements of the Company, and the Trustee assumes no responsibility for the correctness of the same. The Trustee makes no representations as to the validity or sufficiency of this Indenture or of
the Securities. The Trustee shall not be accountable for the use or application by the Company of any Securities or the proceeds of any Securities authenticated and delivered by the Trustee in conformity with this Indenture. The Trustee shall not be
responsible for recording or filing this Indenture, any supplemental indenture, or any financing or continuation statement in any public office at any time or times. 

Section 8.4. Trustee, Authenticating Agent, Paying Agent Or Registrar May Own Securities. The Trustee and any

shall, until used or applied as herein provided, be held in trust for the purposes for which they were received, but need not be segregated from other funds except to the extent required by law. The Trustee may allow and credit to the Company
interest on any money received hereunder at such rate, if any, as may be agreed upon by the Company and the Trustee from time to time as may be permitted by law.

to time, and the Trustee shall be entitled to, reasonable compensation (which shall not be limited by any law in regard to the compensation of a trustee of an express trust), and the Company shall pay or reimburse the Trustee upon its request for
all reasonable expenses, disbursements and advances incurred or made by the Trustee in accordance with this Indenture (including the reasonable compensation and the reasonable expenses and disbursements of its counsel and agents, including any
Authenticating Agents, and of all persons not regularly in its employ) except any such expense, disbursement or advance as may arise from its negligence or bad faith. The Company also covenants to indemnify the Trustee for, and to hold it harmless
against, any loss, liability or expense incurred without negligence or bad faith on the part of the Trustee and arising out of or in connection with the acceptance or administration of this trust, including the costs and expenses of defending itself
against any claim or liability. The obligations of the Company under this Section 8.6 to compensate the Trustee and to pay or reimburse the Trustee for expenses, disbursements and advances shall constitute additional indebtedness hereunder.
Such additional indebtedness shall be secured by a lien prior to that of the Securities upon all property and funds held or collected by the Trustee as such, except funds held in trust for the benefit of the Holders of any particular Securities.


  
 35 








 Section 8.7. Officers’ Certificate As Evidence. Whenever in the
administration of this Indenture, the Trustee shall deem it necessary or desirable that a matter be proved or established prior to the taking, suffering or omitting of any action hereunder, such matter (unless other evidence in respect thereof is
herein specifically prescribed) may, in the absence of negligence or bad faith on the part of the Trustee, be deemed to be conclusively proved and established by an Officers’ Certificate delivered to the Trustee, and such Officers’
Certificate, in the absence of negligence or bad faith on the part of the Trustee, shall be full warrant to the Trustee for any action taken, suffered or omitted by it under this Indenture in reliance thereon. 

Section 8.8. Conflicting Interest Of Trustee. The Trustee shall be subject to and shall comply with the provisions
of Section 31 0 of the TIA; provided that, to the extent permitted by law, Norwest Bank Minnesota, National Association shall not be deemed to have a conflicting interest for purposes of Section 310(b) of the TIA because of its capacity as
trustee under the Company’s pollution control and Resource Recovery bonds. Nothing in this Indenture shall be deemed to prohibit the Trustee or the Company from making any application permitted pursuant to such section. 

Section 8.9. Existence And Eligibility Of Trustee. There shall at all times be a Trustee hereunder which Trustee
shall at all times be a corporation organized and doing business under the laws of the United States or any State thereof or of the District of Columbia (or a corporation or other Person permitted to act as trustee by the Commission), subject to

of each Security outstanding and the Trustee.

under this Section 8.11 as a successor Trustee shall be a bank or trust company eligible under Section 8.9 hereof and qualified under Section 8.8 hereof. 

Section 8.12. Acceptance By Successor Trustee. 

(a) Any successor Trustee appointed as provided in Section 8.11 hereof shall execute, acknowledge and deliver to the
Company and to its predecessor Trustee an instrument accepting such appointment hereunder, and thereupon the resignation or removal of the predecessor Trustee shall become effective and such successor Trustee, without any further act, deed or
conveyance, 

  
 37 








 shall become vested with all the rights, powers, duties and obligations of its predecessor
hereunder, with like effect as if originally named as Trustee herein; but nevertheless, on the written request of the Company or of the successor Trustee, the Trustee ceasing to act shall, upon payment of any amounts then due it pursuant to
Section 8.6 hereof, execute and deliver an instrument transferring to such successor Trustee all the rights and powers of the Trustee so ceasing to act. Upon request of any such successor Trustee, the Company shall execute any and all

shall not have been authenticated, any successor to the Trustee may authenticate such Securities either in the name of any predecessor hereunder or in the name of the successor Trustee; and in all such cases such certificates shall have the full
force which it is anywhere in the Securities or in this Indenture provided that the certificates of the Trustee shall have; provided that the right to adopt the certificate of authentication of any predecessor Trustee or authenticate Securities in
the name of any predecessor Trustee shall apply only to its successor or successors by merger, conversion or consolidation.

 (c) Any Authenticating Agent may at any
time resign by giving written notice of resignation to the Trustee and to the Company. The Trustee may at any time terminate the agency of any Authenticating Agent by giving written notice of termination to such Authenticating Agent and to the
Company. Upon receiving such a notice of resignation or upon such a termination, or in case at any time any Authenticating Agent shall cease to be eligible under this Section 8.15, the Trustee may, with the written consent of the Company,
appoint a successor Authenticating Agent, and upon so doing shall give written notice of such appointment to the Company and shall mail, in the manner provided in Section 14.10, notice of such appointment to the Holders of Securities. ·

Section 9.1. Action By Securityholders. Whenever in this Indenture it is provided that the Holders of a specified
percentage in aggregate principal amount of the Securities may take any action, the fact that at the time of taking any such action the Holders of such specified percentage have joined therein may be evidenced (a) by any instrument or any
number of instruments of similar tenor executed by such Securityholders in person or by agent or proxy appointed in writing, (b) by the record of such Securityholders voting in favor thereof at any meeting of Securityholders duly called and
held in accordance with Article X hereof, or (c) by a combination of such instrument or instruments and any such record of such a meeting of Securityholders. 

Section 9.2. Proof Of Execution By Securityholders. 

(a) Subject to Sections 8.1, 8.2 and 10.5 hereof, proof of the execution of any instruments by a Securityholder or the agent or
proxy for such Securityholder shall be sufficient if made in accordance with such reasonable rules and regulations as may be prescribed by the Trustee or in such manner as shall be satisfactory to the Trustee. The ownership of Securities shall be
proved by the register for the Securities maintained by the Trustee. 
 (b) The record of any Securityholders’ meeting
shall be proven in the manner provided in Section 10.6 hereof. 
 Section 9.3. Who Deemed Absolute Owners.
Subject to Sections 2.4(f) and 9.1 hereof, the Company, the Trustee, any paying agent and any Authenticating Agent shall deem the person in whose name any Security shall be registered upon the register for the Securities to be, and shall treat such
person as, the absolute owner of such Security (whether or not such Security shall be overdue) for the purpose of receiving payment of or on account of the principal and premium, if any, and interest on such Security, and for all other purposes; and
neither the Company nor the Trustee nor any paying agent nor any Authenticating Agent shall be affected by any notice to the contrary. All such payments shall be valid and effectual to satisfy and discharge the liability upon any such Security to
the extent of the sum or sums so paid. 
 Section 9.4. Company-Owned Securities Disregarded. In
determining whether the Holders of the requisite aggregate principal amount of outstanding Securities have concurred in any direction, consent or waiver under this Indenture, Securities which are owned by the Company or any other obligor on the
Securities or by any person directly or indirectly controlling or controlled by or under direct or indirect common control with the Company or any other obligor on the Securities shall be disregarded and deemed not to be outstanding for the purpose
of any such determination; provided that, for the purposes of determining whether the Trustee shall be protected in relying on any such direction, consent or waiver, only Securities which the Trustee 

  
 40 








 knows are so owned shall be so disregarded. Securities so owned which have been pledged in good
faith to third parties may be regarded as outstanding for the purposes of this Section 9.4 if the pledgee shall establish to the satisfaction of the Trustee the pledgee’s right to take action with respect to such Securities and that the
pledgee is not a person directly or indirectly controlling or controlled by or under direct or indirect common control with the Company or any such other obligor. In the case of a dispute as to such right, any decision by the Trustee taken upon the
advice of counsel shall be full protection to the Trustee. 
 Section 9.5. Revocation Of Consents; Future Holders
Bound. Except as may be otherwise required in the case of a Global Security by the applicable rules and regulations of the Depository, at any time prior to the taking of any action by the Holders of the percentage in aggregate principal amount
of the Securities specified in this Indenture in connection with such action, any Holder of a Security, which has been included in the Securities the Holders of which have consented to such action, may, by filing written notice with the Trustee at
the corporate trust office of the Trustee and upon proof of ownership as provided in Section 9.2(a) hereof, revoke such action so far as it concerns such Security. Except as aforesaid, any such action taken by the Holder of any Security shall
be conclusive and binding upon such Holder and upon all future Holders and owners of such Security and of any Securities issued in exchange, substitution or upon registration of transfer therefor, irrespective of whether or not any notation thereof
is made upon such Security or such other Securities. 
 Section 9.6. Record Date For Securityholder Acts. If the
Company shall solicit from the Securityholders any request, demand, authorization, direction, notice, consent, waiver or other act, the Company may, at its option, by Board Resolution, fix in advance a record date for the determination of
Securityholders entitled to give such request, demand, authorization, direction, notice, consent, waiver or other act, but the Company shall have no obligation to do so. If such a record date is fixed, such request, demand, authorization, direction,
notice, consent, waiver or other act may be given before or after the record date, but only the Securityholders of record at the close of business on the record date shall be deemed to be Securityholders for the purpose of determining whether
Holders of the requisite aggregate principal amount of outstanding Securities have authorized or agreed or consented to such request, demand, authorization, direction, notice, consent, waiver or other act, and for that purpose the outstanding
Securities shall be computed as of the record date; provided that no such request, demand, authorization, direction, notice, consent, waiver or other act by the Securityholders on the record date shall be deemed effective unless it shall become
effective pursuant to this Indenture not later than six months after the record date. Any such record date shall be at least 30 days prior to the date of the solicitation to the Securityholders by the Company.

affidavits by one or more persons having knowledge of the facts setting forth a copy of the notice of the meeting and showing that said notice was given as provided in Section 10.2 hereof. The record shall show the aggregate principal amount of
the Securities voting in favor of or against any resolution. The record shall be signed and verified by the affidavits of the permanent chairman and secretary of the meeting and one of the duplicates shall be delivered to the Company and the other
to the Trustee to be preserved by the Trustee and the Trustee shall have the ballots taken at the meeting attached to such duplicate. Any record so signed and verified shall be conclusive evidence of the matters therein stated.

This Global Security is a global security in respect of a duly authorized issue of Debt Securities,
Series             (the “Securities of this Series”, which term includes any Global Securities representing such Securities) of the Company issued and to be issued under an
Indenture dated as of July I, 1999 between the Company and Norwest Bank Minnesota, National Association, as trustee (herein called the “Trustee”, which term includes any successor Trustee under the Indenture) and indentures
supplemental thereto (collectively, the “Indenture”). Under the Indenture, one or more series of Securities may be issued and, as used herein, the term “Securities” refers to the Securities of this Series and any other
outstanding series of Securities. Reference is hereby made for a more complete statement of the respective rights, limitations of rights, duties and immunities under the Indenture of the Company, the Trustee and the Securityholders and of the terms

Each Security of this Series shall be dated and issued as of the date of its authentication by the Trustee and shall bear an
Original Issue Date or Dates. Each Security or Global Security issued upon transfer, exchange or substitution of such Security or Global Security shall bear the Original Issue Date or Dates of such transferred, exchanged or substituted Security or
Global Security, as the case may be. 
 [As applicable, one of the following two sentences: This Global Security may not be
redeemed prior
to                    ,                    . This

this Global Security is redeemable in whole or in part in increments of $1,000 (provided that any remaining principal amount of this Global Security shall be at least $100,000) at the option of the Company at the following redemption prices

required to be paid. 
 The Company, at its option, and subject to the terms and conditions provided in the Indenture, will
be discharged from any and all obligations in respect of the Securities (except for certain obligations including obligations to register the transfer or exchange of Securities, replace stolen, lost or mutilated Securities, maintain paying agencies
and hold monies for payment in trust, all as set forth in the Indenture) if the Company deposits with the Trustee money, U.S. Government Obligations which through the payment of interest thereon and principal thereof in accordance with their terms
will provide money, or a combination of money and U.S. Government Obligations, in any event in an amount sufficient, without reinvestment, to pay all the principal of and any premium and interest on the Securities on the dates such payments are due
in accordance with the terms of the Securities.

 If an Event of Default shall occur and be continuing, the principal of the
Securities may be declared due and payable in the manner and with the effect provided in the Indenture. 
 The Indenture
permits, with certain exceptions as therein provided, the amendment thereof and the modifications of the rights and obligations of the Company and the rights of the Securityholders under the Indenture at any time by the Company and the Trustee with
the consent of the Holders of not less than a majority in principal amount of the outstanding Securities. Any such consent or waiver by the Holder of this Global Security shall be conclusive and binding upon such Holder and upon all future Holders
of this Global Security and of any Security issued upon the registration of transfer hereof or in exchange therefor or in lieu thereof whether or not notation of such consent or waiver is made upon the Security. 

As set forth in and subject to the provisions of the Indenture, no Holder of any Securities will have any right to institute
any proceeding with respect to the Indenture or for any remedy thereunder unless such Holder shall have previously given to the Trustee written notice of a continuing Event of Default with respect to such Securities, the Holders of not less than a

 This Security is one of a duly

Association, as trustee (herein called the “Trustee”, which term includes any successor Trustee under the Indenture) and indentures supplemental thereto (collectively, the “Indenture”). Under the Indenture, one or
more series of Securities may be issued and, as used herein, the term “Securities” refers to the Securities of this Series and any other outstanding series of Securities. Reference is hereby made for a more complete statement of the
respective rights, limitations of rights, duties and immunities under the Indenture of the Company, the Trustee and the Security holders and of the terms upon which the Securities are and are to be authenticated and delivered. This Security is one
of the series designated on the face hereof, limited in aggregate principal amount to 

$                       
 . 
 [As applicable, one of the following two sentences: This Security may not be redeemed prior to

	 Redemption Periods
	  	Redemption Prices

 Notice of redemption
will be given by mail to Holders of Securities of this Series not less than 30 or more than 60 days prior to the date fixed for redemption, all as provided in the Indenture. In the event of redemption of this Security in part only , a new Security
or Securities of this Series of like tenor for the unredeemed portion hereof will be issued in the name of the Security holder hereof upon the surrender hereof. 

Interest payments for this Security shall be computed and paid on the basis of a
360-day year of twelve 30-day months. In any case where any Interest Payment Date or the date on which the principal of this Security is required to be paid is not a
Business Day, then payment of principal, premium or interest need not be made on such date but may be made on the next succeeding Business Day with the same force and effect as if made on such Interest Payment Date or the date on which the principal
of this Security is required to be paid, and, in the case of timely payment thereof, no interest shall accrue for the period from and after such Interest Payment Date or the date on which the principal of this Security is required to be paid. 

The Company, at its option, and subject to the terms and conditions provided in the Indenture, will be discharged from any and
all obligations in respect of the Securities (except for certain obligations including obligations to register the transfer or exchange of Securities, replace 

  
 B-3 








 stolen, lost or mutilated Securities, maintain paying agencies and hold monies for payment in
trust, all as set forth in the Indenture) if the Company deposits with the Trustee money, U.S. Government Obligations which through the payment of interest thereon and principal thereof in accordance with their terms will provide money, or a
combination of money and U.S. Government Obligations, in any event in an amount sufficient, without reinvestment, to pay all the principal of and any premium and interest on the Securities on the dates such payments are due in accordance with the
terms of the Securities. 
 If an Event of Default shall occur and be continuing, the principal of the Securities may be
declared due and payable in the manner and with the effect provided in the Indenture. 
 The Indenture permits, with certain
exceptions as therein provided, the amendment thereof and the modifications of the rights and obligations of the Company and the rights of the Securityholders under the Indenture at any time by the Company and the Trustee with the consent of the
Holders of not less than a majority in principal amount of the outstanding Securities. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any
Security issued upon the registration of transfer hereof or in exchange therefor in lieu thereof whether or not notation of such consent or waiver is made upon the Security. 

As set forth in and subject to the provisions of the Indenture, no Holder of any Securities will have any right to institute
any proceeding with respect to the Indenture or for any remedy thereunder unless such Holder shall have previously given to the Trustee written notice of a continuing Event of Default with respect to such Securities, the Holders of not less than a
majority in principal amount of the outstanding Securities affected by such Event of Default shall have made written request and offered reasonable indemnity to the Trustee to institute such proceeding as Trustee and the Trustee shall have failed to
institute such proceeding within 60 days; provided, however, that such limitations do not apply to a suit instituted by the Holder hereof for the enforcement of payment of the principal of and any premium or interest on this Security on or
after the respective due dates expressed here. 
 No reference herein to the Indenture and to provisions of this Security or
of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of and any premium and interest on this Security at the times, places and rates and the coin or currency prescribed in
the Indenture. 
 As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this
Security is registrable in the Security register. Upon surrender of this Security for registration or transfer at the corporate trust office of the Trustee or such other office or agency as may be designated by the Company in the Borough of
Manhattan, the City and State of New York, endorsed by or accompanied by a written instrument of transfer in form satisfactory to the Company and the Security registrar, duly executed by the Holder hereof or the attorney in fact of such Holder duly
authorized in writing, one or more new Securities of this Series of like tenor and of authorized denominations and for the same aggregate principal amount will be issued to the designated transferee or transferees. 

The Securities of this Series are issuable only in registered form, without coupons, in denominations of $1,000 and any
integral multiple thereof. As provided in the Indenture and 

  
 B-4 








 subject to certain limitations therein set forth, Securities of this Series are exchangeable for
a like aggregate principal amount of Securities of this Series of like tenor and of a different authorized denomination, as requested by the Holder surrendering the same. 

No service charge shall be made for any such registration of transfer or exchange but the Company may require payment of a sum
sufficient to cover any tax or other governmental charge payable in connection therewith. 
 Prior to due presentment of
this Security for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this Security is registered as the owner thereof for all purposes, whether or not this Security is
overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary. 
 The
Indenture and the Securities shall be governed by, and construed in accordance with, the laws of the State of Minnesota. 

All terms used in this Security which are defined in the Indenture shall have the meanings assigned to them in the Indenture.
