        (c)   At
any time and from time to time after the execution and delivery of this Indenture, the Company may deliver Securities executed by the Company to the Trustee for
authentication, together with or preceded by one or more Company Orders for the authentication and delivery of such Securities, and the Trustee in accordance with any such Company Order shall

Section 5.6 prohibiting the declaration or payment of dividends or distributions on, or redemptions, purchases, acquisitions or liquidation payments with respect to, shares of the Company's
Capital Stock shall not be applicable, and (xvii) any other terms of such series not inconsistent with this Indenture. The Securities of all series shall be subordinate to Senior Indebtedness
of the Company as provided in Article XIV. The applicable Board Resolution, Company Order or supplemental indenture may provide that Securities of any particular series may be issued at various
times, with different dates on which the principal or any installment of principal is payable, with different rates of interest, if any, or different methods by which interest may be determined, with
different dates from which such interest shall accrue, with different dates on which such interest may be payable or with any different terms other than Events of Default but all such Securities of a
particular series shall for all purposes under this Indenture including, but not limited to, voting and Events of Default, be treated as Securities of a single series. Unless otherwise expressly
provided with respect to a series of Securities, the aggregate principal amount of a series of Securities may be increased and additional Securities of such series may be issued up to the maximum
aggregate principal amount authorized with respect to such series as increased.

        Prior
to authenticating Securities of any series, and in accepting the additional responsibilities under this Indenture in relation to such Securities, the Trustee shall receive from the
Company the following at or before the issuance of the initial Security of such series of Securities, and (subject to 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: 

        (A)  if
the form of Securities has been established by or pursuant to a Board Resolution, a Company Order 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
such Securities have been duly authorized and executed by the Company, and when authenticated by the Trustee and issued by the Company in the manner and subject to
any conditions specified in such Opinion of Counsel, will constitute valid and binding obligations of the Company, enforceable in accordance with their 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 this Indenture may be limited by state laws
affecting the remedies for the enforcement of the security provided for in this Indenture; and 

        (D)  that
the issuance of the Securities will not result in any default under this Indenture. 

        (3)   an
Officers' Certificate stating that (i) the Company is not, and 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: 

9

 

        (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 15.5 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. 

        Section 2.6    Exchange And Registration Of Transfer Of Securities.    

        (a)   Subject
to Section 2.13 hereof, Securities of any series may be exchanged for one or more new Securities of such series 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 provided in this Article II. 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 of transfer 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. 

10

 

        (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 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 in all respects be entitled to
the same benefits under this Indenture as definitive Securities authenticated and delivered hereunder. 

11

 

        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 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 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)(vii) 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. 

13

 

        (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 2.13 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 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 2.13 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. 

        Section 2.14    Deferrals of Interest Payment Dates.    If specified as contemplated by Section 2.1 or
Section 2.5 with respect to the Securities of a particular series, so long as no Event of Default has occurred and is continuing with respect to such series of Securities, the Company shall
have the right, at any time during the term of such series, from time to time to defer the payment of interest on such Securities for such period or periods as may be specified as contemplated by
Section 2.1 or Section 2.5 (each, an "Extension Period") during which Extension Periods the Company shall have the right to make partial
payments of interest on any Interest Payment Date. The Company shall give the Trustee written notice of its election to make partial payments of interest at least 5 Business Days prior to the
applicable Interest Payment Date. No Extension Period shall end on a date other than an Interest Payment Date or extend beyond the stated maturity. Except as otherwise contemplated in
Section 2.1 or Section 2.5, at the end of any such Extension Period the Company shall pay all interest then accrued and unpaid on such Securities (together with Additional Interest or
other interest thereon, if any, at the rate specified for the Securities of such series to the extent permitted by applicable law). 

        Section 2.15    Agreed Tax Treatment.    Each Security issued hereunder shall provide that the Company and, by
its acceptance of a Security or a beneficial interest therein, the Holder of, and any Person that acquires a beneficial interest in, such Security agree that for United States federal, state
and local tax purposes it is intended that such Security constitute indebtedness. 

        Section 2.16    CUSIP and Other Numbers.    The Company in issuing the Securities may use "CUSIP" numbers, ISIN
numbers or other similar identifiers (if then generally in use), and, if so, the Trustee shall use such numbers in notices of redemption as a convenience to Holders of Securities; provided that
any such notice may state that no representation is made as to the correctness of such numbers either as printed on the Securities or as contained in any notice of a redemption and that reliance may
be placed only on the other identification numbers printed on the Securities, and any such redemption shall not be affected by any defect in or omission of such numbers. The Company will promptly
notify the Trustee of any change in CUSIP, ISIN or other numbers assigned to the Securities.

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. 

        (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 15.10
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 identify the Securities to be redeemed and 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 (including any Additional Interest or other interest) 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 by the Depository for such series of Securities in such manner as the Depository shall determine. Securities shall be redeemed only in minimum
denominations of $1,000 (or as otherwise specified for a series of Securities), provided that any remaining principal amount of a Security redeemed in part shall be a denomination authorized
under this Indenture. 

        (e)   If
at the time of the mailing of any notice of redemption the Company shall not have irrevocably directed the Trustee to apply funds deposited with the Trustee or held
by it and available to be used for the redemption of Securities to redeem all the Securities called for redemption, such notice, at the election of the Company, may state that it is subject to the
receipt of the redemption moneys by the Trustee before the date fixed for redemption and that such notice shall be of no effect unless such moneys are so received before such date. 

15

 

        Section 3.3    Payment Of Securities On Redemption; Deposit Of Redemption Price.    

        (a)   If
notice of redemption for any Securities shall have been given as provided in Section 3.2 hereof and such notice shall not contain the language permitted at the
Company's option under Section 3.2(e) hereof, such Securities or portions of Securities called for redemption shall become due and payable on the date and at the places stated in such notice at
the applicable redemption price, together with interest accrued to the date fixed for redemption of such Securities. Interest on the Securities or portions thereof so called for redemption shall cease
to accrue and such Securities or portions thereof shall be deemed not to be entitled to any benefit under this Indenture except to receive payment of the redemption price together with interest
accrued thereon to the date fixed for redemption or as provided in Article IV. Upon presentation and surrender of such Securities at such a place of payment in such notice specified, such
Securities or the specified portions thereof shall be paid and redeemed at the applicable redemption price, together with interest accrued thereon to the date fixed for redemption. 

        (b)   If
notice of redemption shall have been given as provided in Section 3.2 hereof and such notice shall contain the language permitted at the Company's option under
Section 3.2(e) hereof, such Securities or portions of Securities called for redemption shall become due and payable on the date and at the places stated in such notice at the applicable
redemption price, together with interest accrued to the date fixed for redemption of such Securities, and interest on the Securities or portions thereof so called for redemption shall cease to accrue
and such Securities or portions thereof shall be deemed not to be entitled to any benefit under this Indenture except to receive payment of the redemption price together with interest accrued thereon
to the date fixed for redemption; provided that, in each case, the Company shall have deposited with the Trustee or a paying agent on or prior to such redemption date an amount sufficient to pay the
redemption price together with interest accrued to the date fixed for redemption. Upon the Company making such deposit and, upon presentation and surrender of such Securities at such a place of
payment in such notice specified, such Securities or the specified portions thereof shall be paid and redeemed at the applicable redemption price, together with interest accrued thereon to the date
fixed for redemption. If the Company shall not make such deposit on or prior to the redemption date, the notice of redemption shall be of no force and effect and the principal on such Securities or
specified portions thereof shall continue to bear interest as if the notice of redemption had not been given. 

        (c)   No
notice of redemption of Securities shall be mailed during the continuance of any Event of Default, except (i) that, when notice of redemption of any Securities
has been mailed, the Company shall redeem such Securities but only if funds sufficient for that purpose have prior to the occurrence of such Event of Default been deposited with the Trustee or a
paying agent for such purpose, and (ii) that notices of redemption of all outstanding Securities may be given during the continuance of an Event of Default. 

        (d)   Upon
surrender of any Security redeemed in part only, the Company shall execute, and the Trustee shall authenticate, deliver and register, a new Security or Securities
of authorized denominations in aggregate principal amount equal to, and having the same terms, Original Issue Date or Dates and series as, the unredeemed portion of the Security so surrendered. 

ARTICLE IV

        Section 4.1    Satisfaction and Discharge of Indenture.    If at any time: 

        (a)   the
Company shall have paid or caused to be paid the principal of and premium, if any, and interest on all the outstanding Securities of any series, as and when the same
shall have become due and payable; 

        (b)   the
Company shall have delivered to the Trustee for cancellation all outstanding Securities of such series; or 

16

 

        (c)   the
Company shall have irrevocably deposited or caused to be irrevocably deposited with the Trustee as trust funds the entire amount in (i) cash,
(ii) U.S. Government Obligations maturing as to principal and interest in such amounts and at such times as will insure the availability of cash, or (iii) a combination of cash
and U.S. Government Obligations, in any case sufficient, without reinvestment, as certified by an independent public accounting firm of national reputation in a written certification delivered
to the Trustee, to pay at maturity or the applicable redemption date (provided that notice of redemption shall have been duly given or irrevocable provision satisfactory to the Trustee shall have been
duly made for the giving of any notice of redemption) all outstanding Securities of such series, including principal and any premium and interest due or to become due to such date of maturity, as the
case may be and, unless all outstanding Securities of such series are to be due within 90 days of such deposit by redemption or otherwise, shall also deliver to the Trustee an Opinion of
Counsel to the effect that the Company has received from, or there has been published by, the Internal Revenue Service a ruling or similar pronouncement by the Internal Revenue Service or that there
has been a change of law, in either case to the effect that the Holders of the Securities of such series will not recognize income, gain or loss for federal income tax purposes as a result of such
defeasance or discharge of the Indenture and holders will be subject to tax in the same manner, in the same amounts and at the same time as would have been the case absent such defeasance, and if, in
any such case, the Company shall also pay or cause to be paid all other sums payable hereunder by the Company, then this Indenture shall cease to be of further effect (except as to (A) rights
of registration of transfer and exchange of Securities of such series, (B) substitution of mutilated, defaced, destroyed, lost or stolen Securities of such series, (C) rights of Holders
of Securities of such series to receive payments of principal thereof, and any premium and interest thereon, upon the original stated due dates therefor or upon the applicable redemption date
(but not upon acceleration of maturity) from the moneys and U.S. Government Obligations held by the Trustee pursuant to Section 4.2 hereof, (D) the rights and immunities of
the Trustee hereunder, (E) the rights of the Holders of Securities of such series as beneficiaries hereof with respect to the property so deposited with the Trustee payable to all or any of
them, (F) the obligations and rights of the Trustee and the Company under Section 4.4 hereof, and (G) the duties of the Trustee with respect to any of the foregoing), and the
Company shall be deemed to have paid and discharged the entire indebtedness represented by, and its obligations under, the Securities of such series, and the Trustee, on demand of the Company and at
the cost and expense of the Company, shall execute proper instruments acknowledging such satisfaction of and discharging this Indenture with respect to the Securities of such series and the Trustee
shall at the request of the Company return to the Company all property and money held by it under this Indenture with respect to the Securities of such series and determined by it from time to time in
accordance with the certification pursuant to this Section 4.1(c) to be in excess of the amount required to be held under this Section 4.1. 

        If
the Securities of such series are deemed to be paid and discharged pursuant to Section 4.1(c) hereof, within 15 days after such Securities are so deemed to be paid and
discharged, the Trustee shall cause a written notice provided by the Company to be given to each Holder in the manner provided by Section 15.10 hereof. The notice shall: (i) state that
such Securities are deemed to be paid and discharged; (ii) set forth a description of any U.S. Government Obligations and cash held by the Trustee as described above; and (iii) if
any such Securities will be called for redemption, specify the date or dates on which such Securities are to be called for redemption. 

        Notwithstanding
the satisfaction and discharge of this Indenture with respect to the Securities of any or all series, the obligations of the Company to the Trustee under
Section 8.6 hereof shall survive. 

        Section 4.2    Deposited Moneys To Be Held In Trust By Trustee.    All moneys and U.S. Government
Obligations deposited with the Trustee pursuant to Section 4.1 hereof, shall be held in trust and applied by it to the payment, either directly or through any paying agent (including the
Company acting as its own paying agent), to the Holders of the particular Securities for the payment or redemption of which such moneys and U.S. Government Obligations have been deposited with
the Trustee of all sums due and to become due thereon for principal and premium, if any, and interest. 

        Section 4.3    Paying Agent To Repay Moneys Held.    Upon the satisfaction and discharge of this Indenture with
respect to Securities of any series, all moneys then held by any paying agent for such Securities (other than the Trustee) shall, upon written demand by an Authorized Agent, be repaid to the Company
or paid to the Trustee, and thereupon such paying agent shall be released from all further liability with respect to such moneys. 

        Section 4.4    Return Of Unclaimed Moneys.    Subject to the requirements of applicable law, any moneys
deposited with or paid to the Trustee for payment of the principal of or any premium or interest on any Securities and not applied but remaining unclaimed by the Holders of such Securities for two
years after the date upon which the principal of or any premium or interest on such Securities, as the case may be, shall have become due and payable, shall be repaid to the Company by the Trustee on
written demand by an Authorized Agent, and all liability of the Trustee shall thereupon cease; and any Holder of any of such Securities shall thereafter look only to the Company for any payment which
such Holder may be entitled to collect.

Securities at the places, at the respective times and in the manner provided in such Securities or in this Indenture. 

        Section 5.2    Office For Notices And Payments, Etc.    So long as any of the Securities of any series remain
outstanding, the Company at its option may cause to be maintained in the Borough of Manhattan, the City and State of New York, or elsewhere, an office or agency where the Securities of such
series may be presented for registration of transfer and for exchange as in this Indenture provided, and where, at any time when the Company is obligated to make a payment of principal and premium
upon such Securities, the Securities of such series may be surrendered for payment, and may maintain at any such office or agency and at its principal office an office or agency where notices and
demands to or upon the Company in respect of such Securities or of this Indenture may be served. The designation of any such office or agency shall be made by Company Order pursuant to
Section 2.5 hereof or at any subsequent time pursuant to this Section 5.2 hereof. The Company will give to the Trustee written notice of the location of each such office or agency and of
any change of location thereof. If the Company shall fail to give such notice of the location or of any change in the location of any such office or agency, presentations may be made and notices and
demands may be served at the corporate trust office of the Trustee. 

        Section 5.3    Appointments To Fill Vacancies In Trustee's Office.    The Company, whenever necessary to avoid

        (1)   that
it will hold in trust for the benefit of the Holders and the Trustee all sums held by it as such agent for the payment of the principal of and any premium or

        (2)   that
it will give to the Trustee notice of any failure by the Company (or by any other obligor on such Securities) to make any payment of the principal of and any

        (3)   that
it will at any time during the continuance of any such failure, upon the written request of the Trustee, forthwith pay to the Trustee all sums so held in trust by
such paying agent. 

        If
the Company shall act as its own paying agent with respect to any series of Securities, it will, on or before each due date of the principal of and any premium or interest on such
Securities, set aside, segregate and hold in trust for the benefit of the Holders of such Securities a sum sufficient to pay such principal and any premium or interest so becoming due and will notify
the Trustee of any failure by it to take such action and of any failure by the Company (or by any other obligor on such Securities) to make any payment of the principal of and any premium or
interest on such Securities when the same shall become due and payable. 

        Whenever
the Company shall have one or more paying agents, it will, on or prior to each due date of the principal of (and premium, if any) or interest, if any, on any series of

Persons entitled to such principal, premium or interest, if any, and (unless such paying agent is the Trustee) the Company shall promptly notify the Trustee of any failure on its part to
so act.

for any other reason, pay or cause to be paid to the Trustee all sums held in trust by it or any paying agent hereunder, as required by this Section 5.4, such sums to be held by the Trustee
upon the trusts herein contained. 

        Anything
in this Section 5.4 to the contrary notwithstanding, the agreement to hold sums in trust as provided in this Section 5.4 is subject to Sections 4.3
and 4.4 hereof. 

        Section 5.5    Certificates And Notice To Trustee.    The Company shall, on or before May 1 of each
year, beginning in 2008, deliver to the Trustee a certificate from its principal executive officer, principal financial officer, principal accounting officer, treasurer or assistant treasurer covering
the preceding calendar year and stating whether or not, to the knowledge of such party, the Company has complied with all conditions and covenants under this Indenture, and, if not, describing in
reasonable detail any failure by the Company to comply with any such conditions or covenants. For purposes of this Section 5.5, compliance shall be determined without regard to any period of
grace or requirement of notice provided under this Indenture. 

        Section 5.6    Additional Covenants.    The Company covenants and agrees, to the extent not excluded from the
terms of the series of Securities pursuant to Section 2.5(c)(xvi) hereof, with each Holder of the Securities of any series issued hereunder, that unless the Company shall have paid all accrued
and payable interest on the Securities of such series, except as provided below, it shall not, and shall not permit any of its subsidiaries to: (a) declare or pay any dividends or
distributions, or redeem, purchase, acquire or make a liquidation payment, on any shares of the Company's Capital Stock; (b) make any payment of principal of, or interest or premium, if any, on
or repay, purchase or redeem any of the Company's debt securities that rank upon the Company's liquidation on a parity with or junior to the Securities of such series; or (c) make any payments
with respect to any guarantee by the Company of debt securities if such guarantee ranks upon liquidation on a parity with or junior to the Securities of such series. The foregoing provisions shall not
prevent or restrict the Company from making, and the Company shall be permitted at any time, including during an Extension Period, to make any of the following: (i) purchases, redemptions or
other acquisitions of the Company's Capital Stock in connection with any employment contract, benefit plan or other similar arrangement with or for the benefit of employees, officers, directors,
agents, consultants or a stock purchase, dividend reinvestment or similar plan, or the satisfaction of the Company's obligations pursuant to any contract or security outstanding on the date that the
payment of interest is deferred requiring the Company to purchase, redeem or acquire its Capital Stock; (ii) any payment, repayment, redemption, purchase, acquisition or declaration of a
dividend as a result of any reclassification of the Company's Capital Stock or the exchange or conversion of all or a portion of one class or series of its Capital Stock or debt securities for a class

convertible into or exchangeable for shares of the Company's Capital Stock) and distributions in connection with the settlement of stock purchase contracts outstanding on the date that the payment of
interest on the Securities of such series is deferred as provided in Section 2.14; (v) redemptions, exchanges or repurchases of, or with respect to, any rights outstanding under a
shareholder rights plan or the declaration or payment thereunder of a dividend or distribution of or with respect to rights in the future; and (vi) payments under any trust preferred
securities, subordinated debentures or junior subordinated debentures, or guarantees of the foregoing, in each case that rank equal in right of payment to the Securities of such series, so long as the
amount of payments made on account of such securities or guarantees is paid on all such securities and guarantees then outstanding on a pro rata basis in proportion to the full payment to which
each series of such securities and guarantees is then entitled if paid in full. 

ARTICLE VI

SECURITYHOLDER LISTS AND REPORTS BY THE COMPANY AND THE TRUSTEE  

        Section 6.1    Securityholder Lists.    

        (a)   The
Company shall furnish or cause to be furnished to the Trustee semiannually, not later than the earlier to occur of (i) five days after each Regular Record
Date for each Interest Payment Date that is not a maturity date and (ii) the Business Day prior to such Interest Payment Date, and at such other times as such Trustee may request in writing,
within 30 days after receipt by the Company of any such request, a list in such form as the Trustee may reasonably require containing all the information in the possession or control of the
Company, or any paying agents other than the Trustee, as to the names and addresses of the Holders of Securities, obtained since the date as of which the next previous list, if any, was furnished. Any
such list may be dated as of a date not more than 15 days prior to the time such information is furnished or caused to be furnished and need not include information received after such date;
provided that as long as the Trustee is the registrar for the Securities, no such list shall be required to be furnished. The Trustee shall preserve any list provided to it pursuant to this
Section 6.1 until such time as the Company or any paying agent, as applicable, shall provide it with a more recent list. 

19

 

        (b)   Within
five Business Days after the receipt by the Trustee of a written application by any three or more Holders stating that the applicants desire to communicate with
other Holders with respect to their rights under the Indenture or under the Securities, and accompanied by a copy of the form of proxy or other communication which such applicants propose to transmit,
and by reasonable proof that each such applicant has owned a Security for a period of at least six months preceding the date of such application, the Trustee shall, at its election, either: 

        (1)   afford
to such applicants access to all information furnished to or received by the Trustee pursuant to Section 6.1(a) hereof or, if applicable, in its capacity
as registrar to the Securities; or 

        (2)   inform
such applicants as to the approximate number of Holders according to the most recent information furnished to or received by the Trustee under
Section 6.1(a) hereof or if applicable in its capacity as registrar for the Securities, and as to the approximate cost of mailing to such Holders the form of proxy or other communication, if
any, specified in such application. 

        If
the Trustee shall elect not to afford such applicants access to such information, the Trustee shall, upon the written request of such applicants, mail to each Holder of Securities a
copy of the form of proxy or other communication which is specified in such request, with reasonable promptness after a tender to the Trustee of the material to be mailed and of payment, or provision
for the payment, of the reasonable expenses of such mailing, unless within five Business Days after such tender the Trustee shall mail to such applicants and file with the Commission, together with a
copy of the material to be mailed, a written statement to the effect that, in the opinion of the Trustee, such mailing would be contrary to the best interests of the Holders or would be in violation
of applicable law. Such written statement shall specify the basis of such opinion. If the Commission, after opportunity for a hearing upon the objections specified in the written statement so filed,
shall enter an order refusing to sustain any of such objections or if, after the entry of an order sustaining one or more of such objections, the Commission shall find, after notice and opportunity
for hearing, that all the objections so sustained have been met and shall enter an order so declaring, the Trustee shall mail copies of such material to all Holders with reasonable promptness after
the entry of such order and the renewal of such tender; otherwise the Trustee shall be relieved of any obligation or duty to such applicants respecting their application. 

        (c)   Every
Holder of a Security, by receiving and holding the same, agrees with the Company and the Trustee that neither the Company nor the Trustee nor any paying agent nor
any Authenticating Agent shall be held accountable by reason of the disclosure of any such information as to the names and addresses of the Holders in accordance with this Section 6.1,
regardless of the source from which such information was derived, and that the Trustee shall not be held accountable by reason of mailing any material pursuant to a request made under this
Section 6.1.

ARTICLE VII

REMEDIES OF THE TRUSTEE AND SECURITYHOLDERS ON EVENTS OF DEFAULT  

        Section 7.1    Events Of Default.    

        (a)   If
one or more of the following Events of Default with respect to the Securities of any series shall have occurred and be continuing: 

        (1)   default
in the payment of any installment of interest upon any of the Securities of such series as and when the same shall become due and payable, and continuance of
such default for a period of 30 days (subject to the deferral of any due date in the case of an Extension Period); 

        (2)   default
in the payment of the principal of or any premium on any of the Securities of such series as and when the same shall become due and payable and continuance of
such default for five days; 

21

 

        (3)   failure
on the part of the Company duly to observe or perform any other of the covenants or agreements on the part of the Company contained in the Securities of such
series or in this Indenture (other than a covenant or agreement that has been expressly included in this Indenture solely for the benefit of one or more series of Securities other than such series)
for a period of 90 days after the date on which written notice of such failure, requiring the same to be remedied and stating that such notice is a "Notice of Default" hereunder, shall have
been given to the Company by the Trustee by registered mail, or to the Company and the Trustee by the Holders of at least 33% in aggregate principal amount of the Securities of such series 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 90 consecutive days; 

        (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 the
filing of any such petition or to the appointment of or taking possession by a receiver, liquidator, assignee, trustee, custodian, sequestrator or other similar official of the Company or of any
substantial part of its property, or the failure of the Company generally to pay its debts as such debts become due, or the taking of corporate action by the Company to effectuate any such
action; or 

        (6)   any
other Event of Default specified with respect to Securities of any series pursuant to Section 2.5 hereof; 

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 at least 25% in aggregate
principal amount of the Securities of such series 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 of such series 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 of such series contained to the contrary notwithstanding. 

        The
foregoing paragraph, however, is subject to the condition that if, at any time after the principal of the Securities of any series shall have been so declared due and payable, and
before any judgment or decree for the payment of the moneys due shall have been obtained or entered as hereinafter provided, (i) the Holders of a majority in aggregate principal amount of the
Securities of such series then outstanding, by notice in writing to the Trustee, rescind an acceleration and (ii) the Company shall pay or shall deposit with the Trustee a sum sufficient to pay
all matured installments of interest upon all of the Securities of such series and the principal of and any premium on any and all Securities of such series which shall have become due otherwise than
by acceleration (with interest on overdue installments of interest, to the extent that payment of such interest is enforceable under applicable law, and on such principal and applicable premium at the
rate borne by the Securities of such series 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 of such series which shall have become due solely by acceleration of maturity, shall have been cured or waived, then and in
every such case such Holders' rescission or 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 of such series; but no such waiver or rescission and annulment shall extend to or shall affect any subsequent default, or shall impair any right consequent thereon. 

22

 

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

        Section 7.2    Payment Of Securities On Default; Suit Therefor.    

        (a)   The
Company covenants with respect to the Securities of any series that in case of: 

        (1)   default
in the payment of any installment of interest upon any of the Securities of such series as and when the same shall become due and payable, and continuance of
such default for a period of 30 days (subject to the deferral of any due date in the case of an Extension Period); or 

        (2)   default
in the payment of the principal of or any premium on any of the Securities of such series as and when the same shall have become due and payable whether at the
stated maturity thereof, upon redemption thereof (provided that such redemption is not conditioned upon the deposit of sufficient moneys for such redemption), upon declaration of acceleration
or otherwise, 

then,
upon demand of the Trustee, the Company shall pay to the Trustee, for the benefit of the Holders of the Securities of such series, the whole amount that then shall have so become due and payable
on all such Securities for principal and any premium or interest, or both, as the case may be, with interest upon the overdue principal and any premium and (to the extent that payment of such
interest is enforceable under applicable law) upon the overdue installments of interest at the rate borne by such Securities; and, in addition thereto, such further amounts as shall be sufficient to
cover the costs and expenses of collection, including reasonable compensation to the Trustee, its agents, attorneys and counsel, any expenses or liabilities incurred by the Trustee hereunder other
than through its negligence or 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 such Securities and collect in the manner provided by law out of the property of the Company or any other obligor on such 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 expressed or by declaration or otherwise and irrespective of whether the Trustee shall have made any demand pursuant to this Section 7.2,
shall be entitled and empowered, by intervention in such proceedings or otherwise, to file and prove a 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. 

23

 

        (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 of any series 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. 

        Section 7.3    Application Of Moneys Collected By Trustee.    Any moneys or properties collected by the Trustee
with respect to any of the Securities pursuant to this Article shall be applied in the order following, at the date or dates fixed by the Trustee for the distribution of such moneys, upon presentation
of the several Securities, and stamping thereon the payment, if only partially paid, and upon surrender thereof if fully paid. 

        FIRST:    To
the payment of all amounts due to the Trustee pursuant to Section 8.6 hereof; 

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

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

        FOURTH:    to
the payment of the remainder, if any, to the Company or its successors or assigns, or to whomsoever may lawfully be entitled to the same, or as a court of
competent jurisdiction may determine. 

        Section 7.4    Proceedings By Securityholders.    

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

24

 

        (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 of any series 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 with respect to such Securities; 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
Securities of any series at the time outstanding may on behalf of all of the Holders of the Securities of such series 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 of such series. Upon any such waiver the Company, the Trustee and the Holders of the Securities of such series 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 of such
series 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 of such series, in the manner provided in Section 15.10, 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 of such series, 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 of such series. 

25

 

        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 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.

        (a)   The
Trustee, prior to the occurrence of an Event of Default and after the curing of all Events of Default which may have occurred, undertakes to perform such duties and
only such duties as are specifically set forth in this Indenture. If an Event of Default has occurred (which has not been cured or waived), the Trustee shall exercise such of the rights and powers
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 Indenture, and no implied covenants or obligations shall be read into this Indenture against the Trustee; and 

        (B)  in
the absence of bad faith on the part of the Trustee, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions
expressed therein, upon any certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture; but, in the case of any such certificates or opinions which by 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 in accordance with Section 7.7 hereof relating to the
time, method and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred upon the Trustee under this Indenture. 

        Section 8.2    Reliance On Documents, Opinions, Etc.    Except as otherwise provided in
Section 8.1 hereof: 

        (a)   the

report, notice, request, consent, order, note or other paper or document believed by it to be genuine and to have been signed or presented by the proper party or parties; 

26

 

        (b)   any
request, direction, order or demand of the Company mentioned herein shall be sufficiently evidenced by an Officers' Certificate (unless other evidence in respect
thereof is herein specifically prescribed); and any Board Resolution may be evidenced to the Trustee by a copy thereof certified by the Secretary or an Assistant Secretary of the Company; 

        (c)   the
Trustee may consult with counsel and any advice or Opinion of Counsel shall be full and complete authorization and protection in respect of any action taken,
suffered or omitted by it hereunder in good faith and in accordance with such advice or Opinion of Counsel; 

        (d)   the
Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this Indenture at the request, order or direction of any of the
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;

unless requested in writing to do so by the Holders of at least a majority in principal amount of the then outstanding Securities of any series; 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 liability in the performance of any of its
duties hereunder, or in the exercise of any of its rights or powers, if it shall have reasonable grounds for believing that repayment of such funds or adequate indemnity against such risk or liability
is not reasonably assured to it; and 

        (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.

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.

Agent or paying agent. 

        Section 8.5    Moneys To Be Held In Trust.    Subject to Section 4.4 hereof, all moneys received by the
Trustee 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.

        Section 8.6    Compensation And Expenses Of Trustee.    The Company covenants and agrees to pay to the Trustee
from time to time, and the Trustee shall be entitled to, such compensation as the parties shall agree in writing from time to time for all services rendered to it herein (which compensation 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

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 310 of the TIA; provided that, to the extent permitted by law, Wells Fargo Bank, 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 Trust Indenture, dated December 1, 2000, as supplemented from time to time, between the Company and Wells Fargo
Bank, National Association, as trustee. 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

other Person permitted to act as trustee by the Commission), subject to supervision or examination by such bodies and authorized under such laws to exercise corporate trust powers and having a
combined capital and surplus of at least $150,000,000. If such corporation publishes reports of condition at least annually, pursuant to law or to the requirements of the aforesaid authority, then for
the purposes of this Section 8.9, the combined capital and surplus shall be deemed to be as set forth in its most recent report of condition so published. No obligor upon the Securities or
Person directly or indirectly controlling, controlled by, or under common control with such obligor shall serve as Trustee. If at any time the Trustee shall cease to be eligible in accordance with
this Section 8.9, the Trustee shall resign immediately in the manner and with the effect specified in Section 8.10 hereof. 

 Section 8.10    Resignation Or Removal Of Trustee.  

        (a)   Pursuant
to the provisions of this Article, the Trustee may at any time resign with respect to Securities of any series and be discharged of the trusts with respect to
such Securities created by this Indenture by giving written notice to the Company specifying the day upon which such resignation shall take effect, and such resignation shall take effect immediately
upon the later of the appointment of a successor trustee and such day. 

        (b)   Any
Trustee with respect to Securities of any series may be removed at any time by an instrument or concurrent instruments in writing filed with such Trustee and signed

28

 

        (c)   So
long as no Event of Default has occurred and is continuing, and no event has occurred and is continuing that, with the giving of notice or the lapse of time or both,
would become an Event of Default, the Company may remove any Trustee with respect to Securities of any series upon written notice to the Holder of each outstanding Security of such series and
the Trustee. 

        (d)   If
at any time (1) the Trustee shall cease to be eligible in accordance with Section 8.9 hereof and shall fail to resign after written request therefor by
the Company or by any Holder who has been a bona fide Holder for at least six months, (2) the Trustee shall fail to comply with Section 8.8 hereof after written request therefor
by the Company or any such Holder, or (3) the Trustee shall become incapable of acting or shall be adjudged a bankrupt or insolvent or a receiver of the Trustee or its property shall be
appointed or any public officer shall take charge or control of the Trustee or of its property or affairs for the purpose of rehabilitation, conservation or liquidation, then the Trustee may be
removed forthwith by an instrument or concurrent instruments in writing filed with the Trustee and either: 

        (1)   signed
by the President or any Vice President of the Company and attested by the Secretary or an Assistant Secretary of the Company; or

        (e)   Any
resignation or removal of the Trustee shall not become effective until acceptance of appointment by the successor Trustee as provided in
Section 8.11 hereof. 

        Section 8.11    Appointment Of Successor Trustee.

        (b)   The
Company shall provide written notice of its appointment of a successor Trustee to the Holder of each outstanding Security for any series for which such successor
Trustee is acting as trustee following any such appointment. 

        (c)   If
no appointment of a successor Trustee shall be made pursuant to Section 8.11(a) hereof within 60 days after appointment shall be required, any Holder of
Securities of such series or the resigning Trustee may apply to any court of competent jurisdiction to appoint a successor Trustee. Said court may thereupon after such notice, if any, as such court
may deem proper and prescribe, appoint a successor Trustee. 

        (d)   Any
Trustee appointed 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

        (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, 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
instruments in writing in order more fully and certainly to vest in and confirm to such successor Trustee all such rights and powers. Any Trustee ceasing to act shall, nevertheless, retain a lien upon
all property or funds held or collected by such Trustee to secure any amounts then due it pursuant to Section 8.6 hereof. 

29

 

        (b)   No
successor Trustee shall accept appointment as provided in this Section 8.12 unless at the time of such acceptance such successor Trustee shall be
qualified under Section 8.8 hereof and eligible under Section 8.9 hereof. 

        (c)   Upon
acceptance of appointment by a successor Trustee as provided in this Section 8.12, the successor Trustee shall mail notice of its succession hereunder
to all Holders of Securities as the names and addresses of such Holders appear on the registry books. 

        Section 8.13    Succession By Merger, Etc.    

        (a)   Any
corporation into which the Trustee may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or

this Article. 

        (b)   If
at the time such successor to the Trustee shall succeed to the trusts created by this Indenture any of the Securities shall have been authenticated but not delivered,
any such successor to the Trustee may adopt the certificate of authentication of any predecessor Trustee, and deliver such Securities so authenticated; and in case at that time any of the Securities
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. 

        Section 8.14    Limitations On Rights Of Trustee As A Creditor.    The Trustee shall be subject to, and shall

direction of the Trustee in the authentication and delivery of Securities in connection with transfers and exchanges under Sections 2.6, 2.7, 2.8, 2.13, 3.3, and 12.4 hereof, as fully to
all intents and purposes as though such Authenticating Agents had been expressly authorized by those Sections to authenticate and deliver Securities. For all purposes of this Indenture, the
authentication and delivery of Securities by any Authenticating Agent pursuant to this Section 8.15 shall be deemed to be the authentication and delivery of such Securities "by the Trustee."
Any such Authenticating Agent shall be a bank or trust company or other Person of the character and qualifications set forth in Section 8.9 hereof. 

        (b)   Any
corporation into which any Authenticating Agent may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger,
conversion or consolidation to which any Authenticating Agent shall be a party, or any corporation succeeding to the corporate trust business of any Authenticating Agent, shall be the successor of
such Authenticating Agent hereunder, if such successor corporation is otherwise eligible under this Section 8.15, without the execution or filing of any paper or any further act on the part of
the parties hereto or such Authenticating Agent or such successor corporation. 

        (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

Agent, and upon so doing shall give written notice of such appointment to the Company and shall mail, in the manner provided in Section 15.10, notice of such appointment to the Holders

ARTICLE IX

CONCERNING THE SECURITYHOLDERS  

        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 of any series 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 of any series 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 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 of any series 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. 

31

 

        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.

Holders of Securities of one or more, but less than all, of such series, then the consent of Holders of a majority in aggregate principal amount of the outstanding Securities of all series so directly
affected, considered as one class, shall be required; provided, further, that no such supplemental indenture shall: 

        (1)   change
the maturity date of any Security, or reduce the rate or extend the time of payment of interest thereon, or reduce the principal amount thereof or any premium
thereon, or change the coin or currency in which the principal of any Security or any premium or interest thereon is payable, or change the date on which any Security may be redeemed or repaid at the
option of the Holder thereof or adversely affect the rights of the Securityholders to institute suit for the enforcement of any payment of principal of or any premium or interest on any Security, in
each case without the consent of the Holder of each Security so affected; 

        (2)   modify
this Section 12.2(a) or reduce the aforesaid percentage of Securities, the Holders of which are required to consent to any such supplemental
indenture or to reduce the percentage of Securities, the Holders of which are required to waive Events of Default, in each case, without the consent of the Holders of all of the Securities then
outstanding; or 

        (3)   modify
the provisions of Article XIV with respect to the subordination of outstanding Securities of any series in a manner adverse to the Holders thereof without
the consent of the Holder of each Security so affected.

        (b)   Upon
the request of the Company, accompanied by a copy of the Board Resolution authorizing the execution of any such supplemental indenture, and upon the filing with the
Trustee of evidence of the consent of Securityholders as aforesaid, the Trustee shall join with the Company in the execution of such supplemental indenture unless such supplemental indenture affects
the Trustee's own rights, duties or immunities under this Indenture or otherwise, in which case the Trustee may in its discretion, but shall not be obligated to, enter into such supplemental
indenture. 

        (c)   A
supplemental indenture which changes, waives or eliminates any covenant or provision of this Indenture (or any supplemental indenture) which has expressly been
included solely for the benefit of one or more series of Securities, or which modifies the rights of the Holders of Securities of such series with respect to such covenant or provision, shall be
deemed not to affect the rights under this Indenture of Holders of Securities of any other series. 

        (d)   It
shall not be necessary for the consent of the Holders of Securities under this Section 12.2 to approve the particular form of any proposed supplemental
indenture, but it shall be sufficient if such consent shall approve the substance thereof. 

        (e)   Promptly
after the execution by the Company and the Trustee of any supplemental indenture pursuant to this Section 12.2, the Trustee shall give notice in the
manner provided in Section 15.10 hereof, setting forth in general terms the substance of such supplemental indenture, to all Securityholders. Any failure of the Trustee to give such notice or
any defect therein shall not, however, in any way impair or affect the validity of any such supplemental indenture. 

        Section 12.3    Compliance With Trust Indenture Act; Effect Of Supplemental Indentures.    Any supplemental
indenture executed pursuant to this Article XII shall comply with the TIA. Upon the execution of any supplemental indenture pursuant to this Article XII, the Indenture shall be deemed to
be modified and amended in accordance therewith and the respective rights, limitations of rights, obligations, duties and immunities under this Indenture of the Trustee, the Company and the
Securityholders shall thereafter be determined, exercised and enforced hereunder subject in all respects to such modifications and amendments, and all the terms and conditions of any such supplemental
indenture shall be deemed to be part of the terms and conditions of this Indenture for any and all purposes. 

        Section 12.4    Notation On Securities.    Securities authenticated and delivered after the execution of any
supplemental indenture pursuant to this Article XII may bear a notation in form satisfactory to the Trustee as to any matter provided for in such supplemental indenture. If the Company shall so
determine, new Securities so modified as approved by the Board of Directors and in form satisfactory to the Trustee with respect to any modification of this Indenture contained in any such
supplemental indenture may be prepared and executed by the Company, authenticated by the Trustee and delivered in exchange for the Securities then outstanding. 

        Section 12.5    Evidence Of Compliance Of Supplemental Indenture To Be Furnished Trustee.    The Trustee,
subject to Sections 8.1 and 8.2 hereof, may receive an Officers' Certificate and an Opinion of Counsel as conclusive evidence that any supplemental indenture executed pursuant hereto

of any constitution, statute or rule of law, or by the enforcement of any assessment or penalty or otherwise; it being expressly understood that all such liability is hereby expressly waived and

ARTICLE XIV

SUBORDINATION OF SECURITIES  

        Section 14.1    Agreement To Subordinate.    The Company, for itself, its successors and assigns, covenants and
agrees, and each Holder of a Security of any series likewise covenants and agrees by its acceptance thereof, that the obligation of the Company to make any payment on account of the principal of and
interest on each and all of the Securities of any series shall be subordinate and junior in right of payment to the Company's obligations to the holders of Senior Indebtedness of the Company. 

        In
the case of any insolvency, receivership, conservatorship, reorganization, readjustment of debt, marshaling of assets and liabilities or similar proceedings or any liquidation or
winding-up of or relating to the Company as a whole, whether voluntary or involuntary, all obligations of the Company to holders of Senior Indebtedness of the Company shall be entitled to
be paid in full before any payment shall be made on account of the principal of or interest on any of the Securities. In the event of any such proceeding, after payment in full of all sums owing with
respect to Senior Indebtedness of the Company, the Holders of the Securities of each series, together with the holders of any obligations of the Company ranking on a parity with the Securities, shall
be entitled to be paid from the remaining assets of the Company the amounts at the time due and owing on account of unpaid principal of and interest on the Securities of any series before any payment
or other distribution, whether in cash, property or otherwise, shall be made on account of any capital stock or any obligations of the Company ranking junior to the Securities. In addition, in the
event of any such proceeding, if any payment or distribution of assets of the Company of any kind or character whether in cash, property or securities, including any such payment or distribution which
may be payable or deliverable by reason of the payment of any other indebtedness of the Company being subordinated to the payment of the Securities of any series shall be received by the Trustee or
the Holders of the Securities of any series before all Senior Indebtedness of the Company is paid in full, such payment or distribution shall be held in trust for the benefit of and shall be paid over
to the holders of such Senior Indebtedness of the Company or their representative or representatives or to the trustee or trustees under any indenture under which any instruments evidencing any of
such Senior Indebtedness of the Company may have been issued, ratably, for application to the payment of all Senior Indebtedness of the Company remaining unpaid until all such Senior Indebtedness of
the Company shall have been paid in full, after giving effect to any concurrent payment or distribution to the holders of such Senior Indebtedness of the Company. The obligations of the Company in
respect of the Securities of all series shall rank on a parity with any obligations of the Company ranking on a parity with the Securities. Nothing in this Article shall apply to claims of, or
payments to, the Trustee under or pursuant to Section 8.6. 

        The
subordination provisions of the foregoing paragraph and Section 14.9 shall not be applicable to amounts at the time due and owing on the Securities of any series on account of
the unpaid principal of or interest on the Securities of such series for the payment of which funds have been deposited in trust with the Trustee or any paying agent or have been set aside by the
Company in trust in accordance with the provisions of this Indenture; nor shall such provisions impair any rights, interests, or powers of any secured creditor of the Company in respect of any
security the creation of which is not prohibited by the provisions of this Indenture. 

        The
Company shall give written notice to the Trustee within 10 Business Days after the occurrence of (i) any insolvency, receivership, conservatorship, reorganization,
readjustment of debt, marshaling of assets and liabilities or similar proceedings or any liquidation or winding-up of or relating to the Company as a whole, whether voluntary or
involuntary, (ii) any Event of Default described in Section 7.1(a)(4) or 7.1(a)(5), or (iii) any event specified in Section 14.9. The Trustee, subject to the
provisions of Section 8.1, shall be entitled to assume that, and may act as if, no such event referred to in the preceding sentence has occurred unless a Responsible Officer of the Trustee
assigned to the Trustee's corporate trust department has received at the principal office of the Trustee from the Company or any one or more holders of Senior Indebtedness of the Company or any
trustee or representative therefor (who shall have been certified or otherwise established to the satisfaction of the Trustee to be such a holder or trustee or representative) written notice
thereof. Upon any distribution of assets of the Company referred to in this Article, the Trustee and Holders of the Securities of each series shall be entitled to rely upon any order or decree of a
court of competent jurisdiction in which proceedings relating to any event specified in the first sentence of this paragraph are pending for the purpose of ascertaining the Persons entitled to
participate in such distribution, the holders of the Senior Indebtedness of the Company, the amount thereof or payable thereon, the amount or amounts paid or distributed thereon, and all other facts
pertinent thereto or to this Article, and the Trustee, subject to the provisions of Article VIII, and the Holders of the Securities of each series shall be entitled to rely upon a certificate
of the liquidating trustee or agent or other Person making any distribution to the Trustee or to the Holders of the Securities of each series for the purpose of ascertaining the Persons entitled to
participate in such distribution, the Holders of the Senior Indebtedness of the Company, the amount thereof or payable thereon, the amount or amounts paid or distributed thereon and all other facts
pertinent thereto or to this Article. In the absence of any such liquidating trustee, agent or other Person, the Trustee shall be entitled to rely upon a written notice by a Person representing
himself to be a Holder of Senior Indebtedness of the Company (or a trustee or representative on behalf of such holder) as evidence that such Person is a holder of such Senior Indebtedness
(or is such a trustee or representative). In the event that the Trustee determines, in good faith, that further evidence is required with respect to the right of any Person, as a Holder of
Senior Indebtedness of the Company, to participate in any payment or distribution pursuant to this Article, the Trustee may request such Person to furnish evidence to the reasonable satisfaction of
the Trustee as to the amount of such Senior Indebtedness held by such Person, as to the extent to which such Person is entitled to participation in such payment or distribution, and as to other facts
pertinent to the rights of such Person under this Article, and if such evidence is not furnished, the Trustee may defer any payment to such Person pending judicial determination as to the right of
such Person to receive such payment. 

37

 

        Section 14.2    Obligation Of The Company Unconditional.    Nothing contained in this Article or elsewhere in
this Indenture is intended to or shall impair, as between the Company and the Holders of the Securities of each series, the obligation of the Company, which is absolute and unconditional, to pay to
such Holders the principal of and interest on such Securities of each series when, where and as the same shall become due and payable, all in accordance with the terms of such Securities, or is
intended to or shall affect the relative rights of such Holders and creditors of the Company other than the Holders of the Senior Indebtedness of the Company, nor shall anything herein or therein
prevent the Trustee or the Holder of any Security from exercising all remedies otherwise permitted by applicable law upon default under this Indenture, subject to the rights, if any, under this
Article of the holders of Senior Indebtedness of the Company in respect of cash, property or securities of the Company received upon the exercise of any such remedy. 

        Section 14.3    Limitations On Duties To Holders Of Senior Indebtedness Of The Company.    With respect to the
holders of Senior Indebtedness of the Company, the Trustee undertakes to perform or to observe only such of its covenants and obligations as are specifically set forth in this Article, and no implied
covenants or obligations with respect to the holders of Senior Indebtedness of the Company shall be read into this Indenture against the Trustee. The Trustee shall not be deemed to owe any fiduciary
duty to the holders of Senior Indebtedness of the Company, except with respect to moneys held in trust pursuant to the first paragraph of Section 14.1. 

        Section 14.4    Notice To Trustee Of Facts Prohibiting Payment.    Notwithstanding any of the provisions of
this Article or any other provisions of this Indenture, the Trustee shall not at any time be charged with knowledge of the existence of any facts which would prohibit the making of any payment of
moneys to or by the Trustee unless and until a Responsible Officer of the Trustee assigned to its corporate trust department shall have received at the principal office of the Trustee written notice
thereof from the Company or from one or more holders of Senior Indebtedness of the Company or from any trustee therefor or representative thereof who shall have been certified by the Company or
otherwise established to the reasonable satisfaction of the Trustee to be such a holder or trustee or representative; and, prior to the receipt of any such written notice, the Trustee, subject to the
provisions of Section 8.1, shall be entitled in all respects to assume that no such facts exist; provided, however, that, if prior to the fifth Business Day preceding the date upon which by the
terms hereof any such moneys may become payable for any purpose, or in the event of the execution of an instrument pursuant to Section 4.1 or 4.5 acknowledging satisfaction and discharge
of this Indenture or acknowledging a defeasance or in the event of a deposit under Section 4.5(d)(1) with respect to a covenant defeasance, then, if prior to the second Business Day preceding
the date of such execution or deposit, as the case may be, the Trustee shall not have received with respect to such moneys or the moneys and/or Governmental Obligations deposited pursuant to
Section 4.5 the notice provided for in this Section 14.4, then, anything herein contained to the contrary notwithstanding, the Trustee shall have full power and authority to receive such
moneys and/or Governmental Obligations and/or apply the same to the purpose for which they were received, and shall not be affected by any notice to the contrary which may be received by it on or
after such date; provided, however, no such application shall affect the obligations under this Article of the Persons receiving such moneys from the Trustee. 

38

 

        Section 14.5    Application By Trustee Of Moneys Deposited With It.    Anything in this Indenture to the
contrary notwithstanding, any deposit of moneys by the Company with the Trustee or any agent (whether or not in trust) for any payment of the principal of or interest on any Securities shall, except
as provided in Section 14.4, be subject to the provisions of Section 14.1. 

        Section 14.6    Subrogation.    Subject to the payment in full of all Senior Indebtedness of the Company, the
Holders of the Securities of each series shall be subrogated to the rights of the Holders of such Senior Indebtedness to receive payments or distributions of assets of the Company applicable to such
Senior Indebtedness until the Securities shall be paid in full, and none of the payments or distributions to the Holders of such Senior Indebtedness to which the Holders of the Securities of any
series or the Trustee would be entitled except for the provisions of this Article or of payments over pursuant to the provisions of this Article to the Holders of such Senior Indebtedness by the
Holders of such Securities or the Trustee shall, as among the Company, its creditors other than the Holders of such Senior Indebtedness, and the Holders of such Securities, be deemed to be a payment
by the Company to or on account of such Senior Indebtedness; it being understood that the provisions of this Article are and are intended solely for the purpose of defining the relative rights of the
Holders of such Securities, on the one hand, and the Holders of the Senior Indebtedness of the Company, on the other hand. 

        Section 14.7    Subordination Rights Not Impaired By Acts Or Omissions Of Company Or Holders Of Senior Indebtedness Of The
Company.    No right of any present or future Holders of any Senior Indebtedness of the Company to enforce subordination as herein provided shall at any time in any
way be prejudiced or impaired by any act or failure to act on the part of the Company or by any act or failure to act, in good faith, by any such Holder, or by any noncompliance by the Company with
the terms, provisions and covenants of this Indenture, regardless of any knowledge thereof with which any such Holder may have or be otherwise charged. The Holders of Senior Indebtedness of the
Company may, at any time or from time to time and in their absolute discretion, change the manner, place or terms of payment, change or extend the time of payment of, or renew or alter, any such
Senior Indebtedness of the Company, or amend or supplement any instrument pursuant to which any such Senior Indebtedness of the Company is issued or by which it may be secured, or release any security
therefor, or exercise or refrain from exercising any other of their rights under the Senior Indebtedness of the Company including, without limitation, the waiver of default thereunder, all without
notice to or assent from the Holders of the Securities of each series or the Trustee and without affecting the obligations of the Company, the Trustee or the Holders of such Securities under
this Article. 

        Section 14.8    Authorization Of Trustee To Effectuate Subordination Of Securities.    Each Holder of a
Security of any series, by its acceptance thereof, authorizes and expressly directs the Trustee on its behalf to take such action as may be necessary or appropriate to effectuate, as between the
Holders of such Securities and the holders of Senior Indebtedness of the Company, the subordination provided in this Article and appoints the Trustee as attorney-in-fact for
any and all such purposes. If, in the event of any proceeding or other action relating to the Company referred to in the first sentence of the second paragraph of Section 14.1, the Trustee does
not file a claim or proof of debt in the form required in such proceeding or action is not filed by or on behalf of the Holders of the Securities of any series prior to fifteen days before the
expiration of the time to file such claim or claims, then the holder or holders of Senior Indebtedness of the Company shall have the right to file and are hereby authorized to have the right to and
are (or is) authorized to file in the name of the Trustee, a claim or proof of debt for and on behalf of the Holders of such Securities; provided that (a) if the holder or holders of the
Senior Indebtedness of the Company file any claim or proof of debt as contemplated above and the Trustee shall subsequently file a claim or proof of debt in such proceeding before the
expiration of the time to file a claim or proof of debt in such proceeding, such subsequent claim or proof of debt filed by the Trustee shall supersede any such claim or proof of debt
previously filed by the holder or holders of the Senior Indebtedness of the Company, and such claim or proof of debt previously filed by the holder or holders of the Senior Indebtedness of the Company
shall withdraw such claim or proof of debt, and in any event, such claim or proof of debt shall be deemed to be withdrawn, and (b) the foregoing provisions of this paragraph shall not be
construed to authorize the holder or holders of the Senior Indebtedness of the Company to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, liquidation,
arrangement, adjustment or composition affecting the Securities, or to authorize the holder or holders of the Senior Indebtedness of the Company to vote in respect of the claim of any Holder in any
such proceeding. This paragraph is intended solely to permit the holder or holders of Senior Indebtedness of the Company to preserve their "turnover right" pursuant to the applicable subordination
provisions in this Article XIV in circumstances where a claim or proof of debt has not been filed by the Trustee before the expiration of the time to file a claim or proof of debt in a
bankruptcy proceeding, and nothing herein is intended to impair the rights of the Trustee under Section 7.3 and Section 8.6 of this Indenture. 

39

 

        The
Trustee shall not be deemed to owe any fiduciary duty, or any other duty, to the holder or holders of Senior Indebtedness of the Company and shall not be liable to any such holder or
holders for any action it takes or omits to take within the rights or powers conferred upon it by this Indenture. 

        The
Trustee shall not be responsible for any costs, expenses, damages or other liabilities arising (directly or indirectly) as a result of (i) any filing of a claim or proof of
debt by a holder or holders of Senior Indebtedness of the Company or (ii) any right of the holder or holders of Senior Indebtedness of the Company to file any such claim or proof of debt, in
any such case in accordance with the first paragraph of this Section 14.8. 

        Section 14.9    No Payment When Senior Indebtedness In Default.    In the event and during the continuation of
any default in the payment of principal of or interest on any Senior Indebtedness, or in the event that any event of default with respect to any Senior Indebtedness shall have occurred and be
continuing and shall have resulted in such Senior Indebtedness becoming or being declared due and payable prior to the date on which it would otherwise have become due and payable, unless and until
such event of default shall have been cured, waived or remedied or shall have ceased to exist and such acceleration shall have been rescinded or annulled or all amounts due on such Senior Indebtedness
are paid in full in cash or other permitted consideration, or in the event any judicial proceeding shall be pending with respect to any such default in payment or such event or default (unless and
until all amounts due on such Senior Indebtedness are paid in full in cash or other permitted consideration), then no payment or distribution of any kind or character, whether in cash, properties or
securities shall be made by the Company on account of principal of (or premium, if any) or interest (including any Additional Interest) if any, on the Securities or on account of the purchase
or other acquisition of Securities by the Company or any subsidiary. 

        In
the event that, notwithstanding the foregoing, the Company shall make any payment to the Trustee or the holder of any Security prohibited by the foregoing provisions of this
Section 14.9, and if such fact shall, at or prior to the time of such payment, have been made known to the Trustee or, as the case may be, such Holder, then and in such event payment shall be
paid over and delivered forthwith to the Company. 

        Section 14.10    Right Of Trustee To Hold Senior Indebtedness Of The Company.    The Trustee shall be entitled
to all of the rights set forth in this Article in respect of any Senior Indebtedness of the Company at any time held by it in its individual capacity to the same extent as any other Holder of such
Senior Indebtedness, and nothing in this Indenture shall be construed to deprive the Trustee of any of its rights as such Holder. 

        Section 14.11    Article XIV Not To Prevent Defaults.    The failure of the Company to make a payment
pursuant to the terms of Securities of any series by reason of any provision in this Article shall not be construed as preventing the occurrence of an Event of Default under this Indenture. 

ARTICLE XV

Maturity Date set forth above, and to pay interest thereon from the Original Issue Date (or if this Global Security has
two or more Original Issue Dates, interest shall, beginning on each such Original Issue Date, begin to accrue for that part of the principal amount to which that Original Issue Date is applicable) set
forth above or from the most recent Interest Payment Date to which interest has been paid or duly provided for, semiannually in arrears on the
[                                    ] and
[                                    ] in each year, commencing on the

set forth above, until the principal hereof is paid or made available for payment. No interest shall accrue on the Maturity Date, so long as the principal amount of this Global Security is paid on the
Maturity Date. The interest so payable and punctually paid or duly provided for on any such Interest Payment Date will, as provided in the Indenture, be paid to the Person in whose name this Security
is registered at the close of business on the Regular Record Date for such interest, which shall be the
[                                    ] or
[                                    ], as the
case may be, next preceding such Interest Payment Date; provided, that the first Interest Payment Date for any part of this Security, the Original Issue Date of which is after a Regular Record Date
but prior to the applicable Interest Payment Date, shall be the Interest Payment Date following the next succeeding Regular Record Date; and provided, that interest payable on the Maturity Date set

more than fifteen days or fewer than ten days prior to such Special Record Date. 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 such payment of interest is due on this Global Security (other than maturity), 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 this Global Security and following receipt of the necessary funds from the Company, the Trustee shall deposit with the Depository the amount equal to 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, on the Maturity Date or upon redemption or acceleration, of any part of the principal
and applicable premium of this Global Security, the Depository shall surrender, or cause to be surrendered, this Global Security to the Trustee, whereupon a new Global Security shall be issued to

        This
Global Security is a global security in respect of a duly authorized issue of Junior Subordinated Notes, Series due
[                                    ] (the "Securities
of this Series," which term includes any Global Securities representing such Securities) of the Company issued and to be issued under a Junior Subordinated Indenture dated as of
[                                    ] between the Company and Wells
Fargo Bank, 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. The indebtedness of the Company evidenced by this Global Security, including the principal hereof and interest hereon, is,
to the extent and in the manner set forth in the Indenture, subordinate and junior in right of payment to the Company's obligations to holders of Senior Indebtedness of the Company and each Holder of
this Global Security, by acceptance hereof, agrees to and shall be bound by such provisions of the Indenture and all other provisions of the Indenture. 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 upon which the Securities are
and are to be authenticated and delivered. This Global Security has been issued in respect of the series designated on the first page hereof, limited in aggregate principal amount to
$[                                    ]. 

        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. 

        [Insert
redemption provisions, if applicable] 

        [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 Global Security in part only, a new Global Security or Securities of like tenor and series for the unredeemed portion hereof will be
issued in the name of the Securityholder hereof upon the surrender hereof.] 

        Interest
payments for this Global 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 date on which the principal of this Global 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 date on which the principal of this Global 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 Global 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 of this Series
(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 of this Series. 

A-2

 

        If
an Event of Default shall occur and be continuing, the principal of the Securities of this Series 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 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 Global 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 Global 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, this Global Security may be transferred only as permitted by the legend hereto. 

        If
at any time the Depository for this Global Security notifies the Company that it is unwilling or unable to continue as Depository for this Global Security or if at any time the
Depository for this 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 this Global Security. If a successor Depository for this 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 to issue this Security in global form shall no longer be effective with respect to this Global Security and the Company will
execute, and the Trustee, upon receipt of a Company Order for the authentication and delivery of individual Securities of this Series in exchange for this Global Security, will authenticate and
deliver individual Securities of this Series of like tenor and terms in definitive form in an aggregate principal amount equal to the principal amount of this Global Security. 

        The
Company may at any time and in its sole discretion determine that all Securities of this Series (but not less than all) 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 of this Series in exchange for such Global Security, shall authenticate and deliver, individual Securities of this Series 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. 

        Under
certain circumstances specified in the Indenture, the Depository may be required to surrender any two or more Global Securities which have identical terms (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 all Original Issue Dates and the
principal amount applicable to each such Original Issue Date. 

        The
Indenture and the Securities shall be governed by, and construed in accordance with, the laws of the State of Minnesota. 

A-3

 

        Unless
the certificate of authentication hereon has been executed by the Trustee, directly or through an Authenticating Agent by manual signature of an authorized officer, this Global
Security shall not be entitled to any benefit under the Indenture or be valid or obligatory for any purpose. 

        All
terms used in this Global Security which are defined in the Indenture shall have the meanings assigned to them in the Indenture unless otherwise indicated herein.

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 upon which the Securities are and are to

the name of the Securityholder 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

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

        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

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

        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
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.

[                        ]% JUNIOR SUBORDINATED NOTES, SERIES DUE [        ]

        SECTION 2.01    There shall be a series of Securities designated the "
[                        ]% Junior
Subordinated Notes, Series due [        ]" (the "Notes due [        ]"). The Notes due [        ] shall
be limited to $[                                    ] aggregate
principal amount except as provided in Section 2.08 hereof. 

        SECTION 2.02    Except as otherwise provided in Section 2.05 hereof, the principal amount of the Notes due
[        ] shall be payable on the stated maturity date of [                        ]
(the "Stated Maturity"). 

        SECTION 2.03    The Notes due [        ] shall be dated their date of authentication as
provided in the Indenture. 

        The
Notes due [        ] shall bear interest at (i) the rate of [                        ]
% per annum (the "Fixed Coupon Rate")
up to, but not including, [                        ], (the "Fixed Rate Period"), and (ii) a rate equal to the
Three-Month LIBOR Rate (as defined below) plus
[                        ] basis points (
[                        ]%) per annum, reset quarterly on the LIBOR Rate Reset Dates (as defined below)
(the "Floating Coupon Rate" and, together with the Fixed Coupon Rate, the "Coupon Rate"), from [                        ], to,
 but not including, the Stated Maturity or earlier
Redemption Date (as defined below) (the "Floating Rate Period"), and shall bear interest on any overdue principal at the then-prevailing Coupon Rate and (to the extent
that payment of such interest is enforceable under applicable law) on any overdue or deferred installment of interest at the then-prevailing Coupon Rate, compounded
semi-annually for the Fixed Rate Period and quarterly for the Floating Rate Period, payable (subject to the right of the Company to defer interest payments as described below)
semi-annually in arrears on [                        ] and
[                        ] of each year during the Fixed Rate Period and quarterly in arrears on
[                        ],
[                        ],
[                        ] and
[                        ] of each year during the
Floating Rate Period (each, an "Interest Payment Date"), commencing [                        ] for the Fixed Rate Period and
[                        ] for the Floating
Rate Period, in each case, to the Person in whose name such Note due [        ] is registered at the close of business on the Record Date (as defined below) next
preceding such Interest Payment Date. 

        The
term "Interest Period" shall mean each period from, and including, an Interest Payment Date to, but excluding, the next succeeding Interest Payment Date, except that the first
Interest Period shall commence on the date of original issuance of the Notes due [        ]. 

        During
the Fixed Rate Period, the amount of interest payable for any semi-annual Interest Period shall be computed on the basis of a 360-day year consisting of
twelve 30-day months (and for any period shorter than a full semi-annual period, on the basis of the actual number of days elapsed during such period using
30-day calendar months), and during the Floating Rate Period, the amount of interest payable for any quarterly Interest Period shall be computed by multiplying the Floating Coupon Rate for
that quarterly Interest Period by a fraction, the numerator of which shall be the actual number of days elapsed during that quarterly Interest Period (determined by including the first day of the
Interest Period and excluding the last day), and the denominator of which shall be 360. During the Fixed Rate Period, if an Interest Payment Date or a Redemption Date (as defined below) falls
on a day that is not a Business Day, the payment of interest and principal shall be made on the next succeeding Business Day, and no interest on such payment shall accrue for the period from and after
the Interest Payment Date or Redemption Date, as applicable. During the Floating Rate Period, if any Interest Payment Date, other than a Redemption Date or the Stated Maturity of the Notes due
[        ], falls on a day that is not a Business Day, the Interest Payment Date shall be postponed to the next day that is a Business Day, except that if that Business
Day is in the next succeeding calendar month, the Interest Payment Date shall be the immediately preceding Business Day. Interest will accrue to but excluding the date that interest is actually paid.
During the Floating Rate Period, if a Redemption Date or the Stated Maturity of the Notes due [        ] falls on a day that is not a Business Day, the payment of
interest and principal shall be made on the next succeeding Business Day, and no interest on such payment shall accrue for the period from and after such Redemption Date or the Stated Maturity. 

        During
the Floating Rate Period, if any LIBOR Rate Reset Date (as defined below) falls on a day that is not a Business Day, the LIBOR Rate Reset Date shall be postponed to the
next day that is a Business Day, except that if that Business Day is in the next succeeding calendar month, the LIBOR Rate Reset Date shall be the immediately preceding Business Day. During the
Floating Rate Period, the interest rate in effect on any LIBOR Rate Reset Date shall be the applicable interest rate as reset on that date and the interest rate applicable to any other day shall be
the interest rate as reset on the immediately preceding LIBOR Rate Reset Date.

[                        ] and
[                        ] of each year, commencing
[                        ].
 

        The
"Record Date" for payment of interest will be the Business Day next preceding the Interest Payment Date, unless any such Notes due [        ] are
registered to a Holder other than the Depository or a nominee of the Depository, in which case the Record Date for payment of interest will be the fifteenth calendar day preceding the applicable

U.S. Dollars having a three-month maturity that appears on Reuters LIBOR01 Page as of 11:00 a.m. (London time) on the LIBOR Interest Determination Date for that Interest Period as
determined by the Calculation Agent or its affiliate. If such rate does not appear on the Reuters LIBOR01 Page as of 11:00 a.m. (London time) on the LIBOR Interest Determination Date for
that Interest Period, such Three-Month LIBOR Rate shall be determined on the basis of the rates at which deposits in U.S. Dollars for a three-month period commencing on the applicable LIBOR
Rate Reset Date and ending on the next LIBOR Rate Reset Date (for purposes of this definition, the "Relevant Period") and in a principal amount that is representative for a single transaction
in U.S. dollars in that market at that time are offered to prime banks in the London Inter-Bank Market by the London offices of four major reference banks in the London

effect on that LIBOR Interest Determination Date. The establishment of the Three-Month LIBOR Rate for each Interest Period commencing on or after
[                        ], by the
Calculation Agent or its affiliate shall (in the absence of manifest error) be final and binding.

        The
Company shall have the right, at any time and from time to time during the term of the Notes due [        ], to defer the payment of all or part of the
current and accrued interest for a period not exceeding 10 consecutive years (each period, commencing on the date that the first such payment would otherwise be made, an "Optional Deferral
Period"); provided that no Optional Deferral Period shall extend beyond the Stated Maturity of the Notes due [        ]. During an Optional Deferral Period, interest
(calculated for each Interest Period in the manner provided herein, as if the interest payment had not been so deferred) shall be compounded semi-annually during the Fixed Rate Period and
quarterly during the Floating Rate Period. Any deferred interest on the Notes due [        ] shall accrue interest at a rate equal to the Coupon Rate then applicable to
the Notes due [        ], to the extent permitted by applicable law. At the end of the Optional Deferral Period, the Company shall pay all interest accrued and unpaid
(together with interest thereon) to the person in whose name the Notes due [        ] are registered at the close of business on the Record Date for the Interest Payment
Date on which such Optional Deferral Period ended; provided that any such accrued and unpaid interest payable at the Stated Maturity or any Redemption Date shall be paid to the person to whom
principal is payable. 

        Prior
to the termination of any such Optional Deferral Period, the Company may further defer the payment of interest, provided that such Optional Deferral Period together with all such
previous and further deferrals of interest payments shall not exceed 10 consecutive years at any one time or extend beyond the Stated Maturity of the Notes due
[        ]. Upon the termination of any such Optional Deferral Period and the payment of all amounts then due, including interest on deferred interest payments, the
Company may elect to begin a new Optional Deferral Period, subject to the above requirements. No interest shall be due and payable during an Optional Deferral Period, except at the end thereof. The
Company shall give the Trustee written notice of its election of an Optional Deferral Period at least 10 days and not more than 60 days before the applicable Interest Payment Date. The
Trustee shall promptly forward notice of such election to each Holder of record of the Notes due [        ]. 

        Principal
and interest shall be payable to the persons and in the manner provided in Sections 2.4 and 2.12 of the Indenture. 

        SECTION 2.04    The Notes due [        ] shall be payable at the corporate trust office of
the Trustee at the offices of such paying agents as the Company may appoint by Company Order in the future.

        The
Company may redeem the Notes due [        ] at any time on or after

Price equal to 100% of the principal amount thereof, plus any accrued and unpaid interest thereon to, but not including, the Redemption Date. 

        If
before [                        ], a Tax Event (as defined below) shall occur and be continuing, the Company may redeem the
Notes due
[        ], in whole but not in part, at any time within 90 days following the occurrence of the Tax Event, at a Redemption Price equal to the Tax Event
Make-Whole Amount (as defined below), plus any accrued and unpaid interest thereon to, but not including, the Redemption Date. 

        If
before [                        ], a Rating Agency Event (as defined below) shall occur and be continuing, the Company may
redeem the Notes due
[        ], in whole or from time to time in part, at a Redemption Price equal to the Rating Agency Event Make-Whole Amount (as defined below), plus
any accrued and unpaid interest thereon to, but not including, the Redemption Date.

        For
purposes of this Section 2.05: 

        "Comparable
Treasury Issue" means, with respect to any Redemption Date, the U.S. Treasury security selected by an Independent Investment Banker as having a maturity comparable to
the time period from the Redemption Date to [                        ], that would be utilized, at the time of selection and in
accordance with customary financial practice, in pricing
new issues of corporate debt securities with a term to maturity comparable to such time period. If no U.S. Treasury security has a maturity which is within a period from three months before to
three months after [                        ], the two most closely corresponding U.S. Treasury securities shall be used as
the Comparable Treasury Issue, and the Treasury Yield
(as defined below) shall be interpolated or extrapolated on a straight-line basis, rounding to the nearest month using such securities. 

        "Comparable
Treasury Price" means, with respect to any Redemption Date, (i) the average of the Reference Treasury Dealer Quotations for such Redemption Date, after excluding the
highest and lowest such Reference Treasury Dealer Quotations for such Redemption Date, or (ii) if the Independent Investment Banker obtains fewer than four such Reference Treasury Dealer
Quotations, the average of all such Reference Treasury Dealer Quotations received for such Redemption Date. 

        "Independent
Investment Banker" means [                        ] or their respective successors or, if such firms or their successors are
unwilling or unable to select the
Comparable Treasury Issue, an independent investment banking institution of national standing appointed by the Company. 

        "Make-Whole
Amount" means an amount equal to the greater of (i) 100% of the principal amount of the Notes due [        ] being redeemed
or (ii) the sum of the present values of the remaining scheduled payments of principal and interest on the Notes due [        ] being redeemed from the Redemption
Date to [                        ] (assuming, solely for the purposes of this calculation, that the principal amount of the Notes
due [        ] to be
redeemed was payable on [                        ], and not including any portion of such payments of interest accrued to the
Redemption Date), discounted to the Redemption Date on a
semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at a discount rate equal to the Treasury Yield plus
[                        ] basis points. 

        "Rating
Agency Event" means a change by any nationally recognized statistical rating organization within the meaning of Section 3(a)(62) of the Securities Exchange Act of 1934, as
amended, that publishes a rating for the Company as of [                        ], (and any successor nationally recognized
statistical rating organization) in the equity credit
criteria for securities such as the Notes due [        ] resulting in a lower equity credit to the Company, as certified in an Officer's Certificate to the Trustee by the
Company, than the equity credit assigned by such rating agency to the Notes due [        ] on
[                        ]. 

        "Rating
Agency Event Make-Whole Amount" means an amount equal to the greater of (i) 100% of the principal amount of the Notes due
[        ] being redeemed or (ii) the sum of the present value of each scheduled payment of principal of and interest on the Notes due
[        ] from the Redemption Date to [                        ] (assuming, solely for
the purposes of this calculation, that the principal amount of the
Notes due [        ] to be redeemed was payable on [                        ], and not
including any portion of such payments of interest accrued to the
Redemption Date), discounted to the Redemption Date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at a discount rate equal to
the Treasury Yield plus [                        ] basis points. 

        "Reference
Treasury Dealer" means (i) [                        ] and any other primary U.S. Government securities dealer in
New York City

successors, provided, however, that if
[                        ] or their respective designees cease to be a Primary Treasury Dealer, the Company will appoint another
Primary Treasury Dealer as a substitute and
(ii) any other Primary Treasury Dealer selected by the Company after consultation with the Independent Investment Banker. 

        "Reference
Treasury Dealer Quotations" means, for each Reference Treasury Dealer and any Redemption Date, the average, as determined by the Independent Investment Banker, of the bid and
asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the Independent Investment Banker by such Reference Treasury Dealer
at 5:00 p.m., New York City time, on the third Business Day preceding such Redemption Date. 

5

 

        "Tax
Event" means the receipt by the Company of an Opinion of Counsel experienced in such matters to the effect that, as a result of (i) amendment to or change in the laws or
regulations of the United States or any political subdivision or taxing authority of or in the United States that is enacted or issued or becomes effective after
[                        ]; (ii) proposed change in those laws or regulations that is announced after
[                        ]; (iii) official
administrative decision or judicial decision or administrative action or other official pronouncement interpreting or applying those laws or regulations that is announced after
[                        ]; or (iv) threatened challenge asserted in writing in connection with an audit of the Company or
its subsidiaries, or a threatened challenge asserted in
writing against any other taxpayer that has raised capital through the issuance of securities that are substantially similar to the Notes due [        ], which amendment,
clarification, or change is effective, or which Administrative Action is taken or which judicial decision, interpretation or pronouncement is issued, in each case after
[                        ], there is more than an insubstantial risk that interest payable by the Company on the Notes due
[        ] is not deductible, or
within 90 days would not be deductible, in whole or in part, by the Company for U.S. federal income tax purposes. 

        "Tax
Event Make-Whole Amount" means an amount equal to the greater of (i) 100% of the principal amount of the Notes due [        ] being
redeemed or (ii) the sum of the present value of each scheduled payment of principal of and interest on the Notes due [        ] from the Redemption Date to
[                        ], (assuming, solely for the purposes of this calculation, that the principal amount of the Notes due
[        ] to be redeemed
was payable on [                        ], and not including any portion of such payments of interest accrued to the Redemption
Date), discounted to the Redemption Date on a
semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at a discount rate equal to the Treasury Yield plus
[                        ] basis points. 

        "Treasury
Yield" means, for any Redemption Date, (i) the yield, under the heading which represents the average for the immediately preceding week, appearing in the most recently
published statistical release designated "H.15(519)" or any successor publication which is published weekly by the Board of Governors of the Federal Reserve System and which establishes yields on
actively traded U.S. Treasury securities adjusted to constant maturity under the caption "Treasury Constant Maturities," for the maturity corresponding to the Comparable Treasury Issue
(if no maturity is within three months before or after such time period, yields for the two published maturities most closely corresponding to the Comparable Treasury Issue shall be determined
and the Treasury Yield shall be interpolated or extrapolated from such yields on a straight-line basis, rounding to the nearest month) or (ii) if such release (or any
successor release) is not published during the week preceding the calculation date or does not contain such yields, the rate per annum equal to the semi-annual equivalent yield to maturity
of the Comparable Treasury Issue, calculated using a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such
Redemption Date. The Treasury Yield shall be calculated on the third Business Day preceding the Redemption Date. 

        Promptly
after the calculation of the Redemption Price of the Notes due, the Company shall give the Trustee notice thereof and the Trustee shall have no responsibility for any such
calculation. 

        The
Notes due [        ] shall not be subject to any sinking fund. 

        SECTION 2.06    The Notes due [        ] shall be issued in fully registered form without
coupons in denominations of $2,000 and in integral multiples of $1,000 in excess thereof. 

        SECTION 2.07    The Notes due [        ] shall initially be in the form attached as
Exhibit A hereto. 

        SECTION 2.08    The Notes due [        ] may be reopened and additional notes of the Notes
due [        ] may be issued in excess of the limitation set forth in Section 2.01, provided that such additional notes will contain the same terms (including the
maturity date and interest payment terms) as the other Notes due [        ]. Any such additional Notes due [        ], together with the
other Notes due [        ], shall constitute a single series for purposes of the Indenture. 

6

 

        SECTION 2.09    In addition to the restrictions on the Notes due [        ] contained in
the Indenture, unless the Company shall have paid all accrued and payable interest on the Notes due [        ], except as provided below, the Company shall not, and shall
not permit any of its subsidiaries to: (a) declare or pay any dividends or distributions, or redeem, purchase, acquire or make a liquidation payment, on any shares of the Company's Capital
Stock; (b) make any payment of principal of, or interest or premium, if any, on or repay, purchase or redeem any of the Company's debt securities that rank upon the Company's liquidation on a
parity with or junior to the Notes due [        ] (provided that the Company may make partial payment of interest on the Notes due
[        ]); or (c) make any payments with respect to any guarantee by the Company of debt securities if such guarantee ranks upon liquidation on a parity with or
junior to the Notes due [        ]. The foregoing provisions shall not prevent or restrict the Company from making, and the Company shall be permitted at any time,
including during an Optional Deferral Period, to make any of the following: (i) purchases, redemptions or other acquisitions of the Company's Capital Stock in connection with any employment
contract, benefit plan or other similar arrangement with or for the benefit of employees, officers, directors, agents, consultants or a stock purchase, dividend reinvestment or similar plan, or the
satisfaction of the Company's obligations pursuant to any contract or security outstanding on the date that the payment of interest is deferred requiring the Company to purchase, redeem or acquire its
Capital Stock; (ii) any payment, repayment, redemption, purchase, acquisition or declaration of a dividend as a result of any reclassification of the Company's Capital Stock or the exchange or
conversion of all or a portion of one class or series of its Capital Stock or debt securities for a class or series of its Capital Stock; (iii) the purchase of fractional interests in shares of
the Company's Capital Stock pursuant to the conversion or exchange provisions of its Capital Stock or the security being converted or exchanged, or in connection with the settlement of stock purchase
contracts; (iv) dividends or distributions paid or made in the Company's Capital Stock (or rights to acquire its Capital Stock), or repurchases, redemptions or acquisitions of Capital
Stock in connection with the issuance or exchange of Capital Stock (or of securities convertible into or exchangeable for shares of the Company's Capital Stock) and distributions in connection
with the settlement of stock purchase contracts outstanding on the date that the payment of interest on the Notes due [        ] is deferred; (v) redemptions,
exchanges or repurchases of, or with respect to, any rights outstanding under a shareholder rights plan or the declaration or payment thereunder of a dividend or distribution of or with respect to
rights in the future; and (vi) payments under any trust preferred securities, subordinated debentures or junior subordinated debentures, or guarantees of the foregoing, in each case that rank
equal in right of payment to the Notes due [        ], so long as the amount of payments made on account of such securities or guarantees is paid on all such securities
and guarantees then outstanding on a pro rata basis in proportion to the full payment to which each series of such securities and guarantees is then entitled if paid in full. 

        SECTION 2.10    Notwithstanding anything to the contrary in the Indenture, in no event will the occurrence or
continuation of an event described in Section 7.1(a)(3) of the Indenture constitute an Event of Default.

        XCEL
ENERGY INC., a corporation of the State of Minnesota (the "Company"), for value received hereby promises to pay to Cede & Co. or registered assigns, the
principal sum of [                                    ] DOLLARS on the
Maturity Date set forth above (the "Stated Maturity"), and to pay interest thereon from the Original Issue Date
(or if this Global Security has two or more Original Issue Dates, interest shall, beginning on each such Original Issue Date, begin to accrue for that part of the principal amount to which that
Original Issue Date is applicable) set forth above or from the most recent Interest Payment Date to which interest has been paid or duly provided for, as set forth below. The Securities of this Series
(as defined below) shall bear interest at (i) the rate of [                        ]% per annum (the "Fixed Coupon
Rate") up to, but not including,
[                        ], (the "Fixed Rate Period"), and (ii) a rate equal to the Three-Month LIBOR Rate
(as defined below) plus
[                        ] basis points (
[                        ]%) per annum, reset quarterly on the LIBOR Rate Reset Dates (as defined below)
(the "Floating Coupon Rate" and, together with the Fixed Coupon Rate, the "Coupon Rate"), from [                        ] up
to, but not including, the Stated Maturity or earlier
Redemption Date (as defined below) (the "Floating Rate Period"), and shall bear interest on any overdue principal at the then-prevailing Coupon Rate and (to the extent
that payment of such interest is enforceable under applicable law) on any overdue or deferred installment of interest at the then-prevailing Coupon Rate, compounded
semi-annually for the Fixed Rate Period and quarterly for the Floating Rate Period, payable (subject to the right of the Company to defer interest payments as described below)
semi-annually in arrears on [                        ] and
[                        ] of each year during the Fixed Rate Period and quarterly in arrears on
[                        ],
[                        ],
[                        ] and
[                        ] of each year during the
Floating Rate Period (each, an "Interest Payment Date"), commencing [                        ] for the Fixed Rate Period and
[                        ] for the Floating
Rate Period, in each case, to the Person in whose name such Security of this Series is registered at the close of business on the Record Date (as defined below) next preceding such Interest
Payment Date. 

A-1

 

        The
term "Interest Period" shall mean each period from, and including, an Interest Payment Date to, but excluding, the next succeeding Interest Payment Date, except that the first
Interest Period shall commence on the date of original issuance of the Securities of this Series. 

        During
the Fixed Rate Period, the amount of interest payable for any semi-annual Interest Period shall be computed on the basis of a 360-day year consisting of
twelve 30-day months (and for any period shorter than a full semi-annual period, on the basis of the actual number of days elapsed during such period using
30-day calendar months), and during the Floating Rate Period, the amount of interest payable for any quarterly Interest Period shall be computed by multiplying the Floating Coupon Rate for
that quarterly Interest Period by a fraction, the numerator of which shall be the actual number of days elapsed during that quarterly Interest Period (determined by including the first day of the
Interest Period and excluding the last day), and the denominator of which shall be 360. During the Fixed Rate Period, if an Interest Payment Date or a Redemption Date (as defined below) falls
on a day that is not a Business Day, the payment of interest and principal shall be made on the next succeeding Business Day, and no interest on such payment shall accrue for the period from and after
the Interest Payment Date or Redemption Date, as applicable. During the Floating Rate Period, if any Interest Payment Date, other than a Redemption Date or the Stated Maturity of the Securities of
this Series, falls on a day that is not a Business Day, the Interest Payment Date shall be postponed to the next day that is a Business Day, except that if that Business Day is in the next succeeding
calendar month, the Interest Payment Date shall be the immediately preceding Business Day. Interest will accrue to but excluding the date that interest is actually paid. During the Floating Rate
Period, if a Redemption Date or the Stated Maturity of the Securities of this Series falls on a day that is not a Business Day, the payment of interest and principal shall be made on the next
succeeding Business Day, and no interest on such payment shall accrue for the period from and after such Redemption Date or the Stated Maturity. 

        During
the Floating Rate Period, if any LIBOR Rate Reset Date (as defined below) falls on a day that is not a Business Day, the LIBOR Rate Reset Date shall be postponed to the
next day that is a Business Day, except that if that Business Day is in the next succeeding calendar month, the LIBOR Rate Reset Date shall be the immediately preceding Business Day. During the
Floating Rate Period, the interest rate in effect on any LIBOR Rate Reset Date shall be the applicable interest rate as reset on that date and the interest rate applicable to any other day shall be
the interest rate as reset on the immediately preceding LIBOR Rate Reset Date. 

        "Business
Day" means each Monday, Tuesday, Wednesday, Thursday and Friday that is not a day on which banking institutions or trust companies in the Borough of Manhattan, the City and
State of New York, or in the city where the corporate trust office of the Trustee is located, are obligated or authorized by law or executive order to close. 

        "Calculation
Agent" means a banking institution or trust company appointed by the Company to act as calculation agent. 

        "LIBOR
Business Day" means any business day on which dealings in deposits in U.S. Dollars are transacted in the London Inter-Bank Market. 

        "LIBOR
Interest Determination Date" means the second LIBOR Business Day preceding each LIBOR Rate Reset Date. 

        "LIBOR
Rate Reset Date" means [                        ],
[                        ],
[                        ] and
[                        ] of each year, commencing
[                        ] if any LIBOR Rate Reset Date (as defined below) falls on a day that is not a
Business Day, the LIBOR Rate Reset Date shall be postponed to the next day that is a Business Day, except that if that Business Day is in the next succeeding calendar month, the LIBOR Rate Reset Date
shall be the immediately preceding Business Day. 

A-2

 

        The
"Record Date" for payment of interest will be the Business Day next preceding the Interest Payment Date, unless any such Securities of this Series are registered to a Holder other
than the Depository or a nominee of the Depository, in which case the Record Date for payment of interest will be the fifteenth calendar day preceding the applicable Interest Payment Date, whether or
not a Business Day. 

        "Redemption
Date" means the date fixed for such redemption by or pursuant to the provisions hereof. 

        "Reuters
LIBOR01 Page" means the display designated on page LIBOR01 on Reuters Page (or such other page as may replace the LIBOR01 page on such service or
such other service as may be nominated by the British Bankers' Association for the purpose of displaying London Inter-Bank offered rates for U.S. Dollar deposits). 

        "Reuters
Page" means the display on Reuters Money 3000 Service, or any successor service, on the Reuters LIBOR01 Page or any replacement page or pages on
that service. 

        "Three-Month
LIBOR Rate" means, with respect to each Interest Period commencing on a LIBOR Rate Reset Date, the rate (expressed as a percentage per annum) for deposits in
U.S. Dollars having a three-month maturity that appears on Reuters LIBOR01 Page as of 11:00 a.m. (London time) on the LIBOR Interest Determination Date for that Interest Period as
determined by the Calculation Agent or its affiliate. If such rate does not appear on the Reuters LIBOR01 Page as of 11:00 a.m. (London time) on the LIBOR Interest Determination Date for
that Interest Period, such Three-Month LIBOR Rate shall be determined on the basis of the rates at which deposits in U.S. Dollars for a three-month period commencing on the applicable LIBOR
Rate Reset Date and ending on the next LIBOR Rate Reset Date (for purposes of this definition, the "Relevant Period") and in a principal amount that is representative for a single transaction
in U.S. dollars in that market at that time are offered to prime banks in the London Inter-Bank Market by the London offices of four major reference banks in the London
Inter-Bank Market, selected by the Calculation Agent or its affiliate (after consultation with the Company), at approximately 11:00 a.m., London time on the LIBOR Interest
Determination Date for that Interest Period. The Calculation Agent or its affiliate shall request the principal London office of each of such banks to provide a quotation of its rate. If at least two
such quotations are provided, then the Three-Month LIBOR Rate with respect to that Interest Period shall be the arithmetic average (rounded, if necessary, to the nearest one-hundredth
(0.01) of a percent) of such quotations. If fewer than two quotations are provided, then the Three-Month LIBOR Rate with respect to that Interest Period shall be the arithmetic average (rounded, if
necessary, to the nearest one-hundredth (0.01) of a percent) of the rates quoted by three major banks in New York City, selected by the Calculation Agent or its affiliate (after
consultation with the Company), at approximately 11:00 a.m., New York City time, on the LIBOR Interest Determination Date for loans in U.S. Dollars to leading European banks for
the Relevant Period and in a principal amount that is representative for a single transaction in U.S. dollars in that market at that time. However, if fewer than three banks selected by the
Calculation Agent or its affiliate to provide quotations are quoting in the manner described above, the Three-Month LIBOR Rate for that Interest Period shall be the rate in effect on that LIBOR
Interest Determination Date. The establishment of the Three-Month LIBOR Rate for each Interest Period commencing on or after
[                        ] by the Calculation Agent or its
affiliate shall (in the absence of manifest error) be final and binding. 

        The
Company shall have the right, at any time and from time to time during the term of the Securities of this Series, to defer the payment of all or part of the current and accrued
interest for a period not exceeding 10 consecutive years (each period, commencing on the date that the first such payment would otherwise be made, an "Optional Deferral Period"); provided that
no Optional Deferral Period shall extend beyond the Stated Maturity of the Securities of this Series. During an Optional Deferral Period, interest (calculated for each Interest Period in the manner
provided herein, as if the interest payment had not been so deferred) shall be compounded semi-annually during the Fixed Rate Period and quarterly during the Floating Rate Period. Any
deferred interest on the Securities of this Series shall accrue interest at a rate equal to the Coupon Rate then applicable to the Securities of this Series, to the extent permitted by applicable law.
At the end of the Optional Deferral Period, the Company shall pay all interest accrued and unpaid (together with interest thereon) to the person in whose name the Securities of this Series are
registered at the close of business on the Record Date for the Interest Payment Date on which such Optional Deferral Period ended; provided that any such accrued and unpaid interest payable at the
Stated Maturity or any Redemption Date shall be paid to the person to whom principal is payable. 

A-3

 

        Prior
to the termination of any such Optional Deferral Period, the Company may further defer the payment of interest, provided that such Optional Deferral Period together with all such
previous and further deferrals of interest payments shall not exceed 10 consecutive years at any one time or extend beyond the Stated Maturity of the Securities of this Series. Upon the
termination of any such Optional Deferral Period and the payment of all amounts then due, including interest on deferred interest payments, the Company may elect to begin a new Optional Deferral
Period, subject to the above requirements. No interest shall be due and payable during an Optional Deferral Period, except at the end thereof. The Company shall give the Trustee written notice of its
election of an Optional Deferral Period at least 10 days and not more than 60 days before the applicable Interest Payment Date. The Trustee shall promptly forward notice of such election
to each Holder of record of the Securities of this Series. 

        Principal
and interest shall be payable to the persons and in the manner provided in Sections 2.4 and 2.12 of the Indenture (as defined below). 

        This
Global Security is a global security in respect of a duly authorized issue of Junior Subordinated Notes, Series due
[                        ] (the "Securities

this Global Security, by acceptance hereof, agrees to and shall be bound by such provisions of the Indenture and all other provisions of the Indenture. Reference is hereby made to the Indenture 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 upon which the
Securities of this Series are and are to be authenticated and delivered. This Global Security has been issued in respect of the series designated on the first page hereof.

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. 

        The
Company may redeem the Securities of this Series at any time before [                        ] in whole or from time to time in
part, at a Redemption Price
(as defined below) equal to the Make-Whole Amount (as defined below), plus any accrued and unpaid interest thereon to, but not including, the Redemption Date. 

        The
Company may redeem the Securities of this Series at any time on or after [                        ] in whole or in part, at a
Redemption Price equal to 100% of the
principal amount thereof, plus any accrued and unpaid interest thereon to, but not including, the Redemption Date. 

        If
before [                        ] a Tax Event (as defined below) shall occur and be continuing, the Company may redeem the
Securities of this Series, in whole
but not in part, at any time within 90 days following the occurrence of the Tax Event, at a Redemption Price equal to the Tax Event Make-Whole Amount (as defined below), plus
any accrued and unpaid interest thereon to, but not including, the Redemption Date. 

        If
before [                        ] a Rating Agency Event (as defined below) shall occur and be continuing, the Company may
redeem the Securities of this Series,
in whole or from time to time in part, at a Redemption Price equal to the Rating Agency Event Make-Whole Amount (as defined below), plus any accrued and unpaid interest thereon to,
but not including, the Redemption Date. 

A-4

 

        "Comparable
Treasury Issue" means, with respect to any Redemption Date, the U.S. Treasury security selected by an Independent Investment Banker as having a maturity comparable to
the time period from the Redemption Date to [                        ] that would be utilized, at the time of selection and in
accordance with customary financial practice, in pricing
new issues of corporate debt securities with a term to maturity comparable to such time period. If no U.S. Treasury security has a maturity which is within a period from three months before to
three months after [                        ] the two most closely corresponding U.S. Treasury securities shall be used as
the Comparable Treasury Issue, and the Treasury Yield
(as defined below) shall be interpolated or extrapolated on a straight-line basis, rounding to the nearest month using such securities. 

        "Comparable
Treasury Price" means, with respect to any Redemption Date, (i) the average of the Reference Treasury Dealer Quotations for such Redemption Date, after excluding the
highest and lowest such Reference Treasury Dealer Quotations for such Redemption Date, or (ii) if the Independent Investment Banker obtains fewer than four such Reference Treasury Dealer
Quotations, the average of all such Reference Treasury Dealer Quotations received for such Redemption Date. 

        "Independent
Investment Banker" means [                        ] or their respective successors or, if such firms or their successors are

Comparable Treasury Issue, an independent investment banking institution of national standing appointed by the Company. 

        "Make-Whole

        In
addition to the restrictions on the Securities of this Series contained in the Indenture, unless the Company shall have paid all accrued and payable interest on the Securities of this

a liquidation payment, on any shares of the Company's Capital Stock; (b) make any payment of principal of, or interest or premium, if any, on or repay, purchase or redeem any of the Company's

any of the following: (i) purchases, redemptions or other acquisitions of the Company's Capital Stock in connection with any employment contract, benefit plan or other similar arrangement with

contracts outstanding on the date that the payment of interest on the Securities of this Series is deferred; (v) redemptions, exchanges or repurchases of, or with respect to, any rights
outstanding under a shareholder rights plan or the declaration or payment thereunder of a dividend or distribution of or with respect to rights in the future; and (vi) payments under any trust
preferred securities, subordinated debentures or junior subordinated debentures, or guarantees of the foregoing, in each case that rank equal in right of payment to the Securities of this Series, so
long as the amount of payments made on account of such securities or guarantees is paid on all such securities and guarantees then outstanding on a pro rata basis in proportion to the full
payment to which each series of such securities and guarantees is then entitled if paid in full. 

        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 of this Series
(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 of this Series. 

        If
an Event of Default with respect to the Securities of this Series shall occur and be continuing, the principal of the Securities of this Series may be declared due and payable in the
manner and with the effect provided in the Indenture; provided, however, that notwithstanding anything to the contrary in the Indenture, in no event will the occurrence or continuation of an event
described in 7.1(a)(3) of the Indenture constitute an Event of Default with respect to the Securities of this Series. 

        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. 

        No
reference herein to the Indenture and to provisions of this Global 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 Global 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, this Global Security may be transferred only as permitted by the legend hereto. 

        If
at any time the Depository for this Global Security notifies the Company that it is unwilling or unable to continue as Depository for this Global Security or if at any time the
Depository for this 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 this Global Security. If a successor Depository for this 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 to issue this Security in global form shall no longer be effective with respect to this Global Security and the Company will
execute, and the Trustee, upon receipt of a Company Order for the authentication and delivery of individual Securities of this Series in exchange for this Global Security, will authenticate and
deliver individual Securities of this Series of like tenor and terms in definitive form in an aggregate principal amount equal to the principal amount of this Global Security. 

        The
Company may at any time and in its sole discretion determine that all Securities of this Series (but not less than all) 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 of this Series in exchange for such Global Security, shall authenticate and deliver, individual Securities of this Series 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. 

        Under
certain circumstances specified in the Indenture, the Depository may be required to surrender any two or more Global Securities which have identical terms (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 all Original Issue Dates and the
principal amount applicable to each such Original Issue Date. 

        The
Indenture and the Securities shall be governed by, and construed in accordance with, the laws of the State of Minnesota. 

        Unless
the certificate of authentication hereon has been executed by the Trustee, directly or through an Authenticating Agent by manual signature of an authorized officer, this Global
Security shall not be entitled to any benefit under the Indenture or be valid or obligatory for any purpose. 

        All
terms used in this Global Security which are defined in the Indenture shall have the meanings assigned to them in the Indenture unless otherwise indicated herein.
