THIS THIRD SUPPLEMENTAL INDENTURE (this “Third
Supplemental Indenture”), dated as of August 3, 2021, is between Golub Capital BDC, Inc., a Delaware corporation (the

RECITALS OF THE COMPANY


 


The Company and the Trustee executed and delivered
an Indenture, dated as of October 2, 2020 (the “Base Indenture” and, as amended and supplemented by this Third
Supplemental Indenture, the “Indenture”), to provide for the issuance by the Company from time to time of the Company’s
secured or unsecured indebtedness (the “Securities”), to be issued in one or more series as provided in the Indenture.


 


The Company desires to issue and sell $350,000,000
aggregate principal amount of the Company’s 2.050% Notes due 2027 (the “Notes”).


 


The Company previously entered
into the First Supplemental Indenture, dated as of October 2, 2020 (the “First Supplemental Indenture”), and the
Second Supplemental Indenture, dated as of February 24, 2021 (the “Second Supplemental Indenture”), both of which
amended and supplemented the Base Indenture. The First Supplemental Indenture and Second Supplemental Indenture are not applicable
to the Notes.


 


Sections 9.01(iv) and 9.01(vi) of the
Base Indenture provide that without the consent of Holders of the Securities of any series issued under the Indenture, the Company, when
authorized by or pursuant to a Board Resolution, and the Trustee, at any time and from time to time, may enter into one or more indentures
supplemental to the Base Indenture to (i) change or eliminate any of the provisions of the Indenture when there is no Security Outstanding
of any series created prior to the execution of the supplemental indenture that is entitled to the benefit of such provision and (ii) establish
the form or terms of Securities of any series as permitted by Section 2.01 and Section 3.01 of the Base Indenture.


 






     


     


    

 


The Company desires to establish the form and terms
of the Notes and to modify, alter, supplement and change certain provisions of the Base Indenture for the benefit of the Holders of the
Notes (subject to amendment as may be provided in a future supplemental indenture to the Indenture (“Future Supplemental Indenture”)).


 


The Company has duly authorized the execution and
delivery of this Third Supplemental Indenture to provide for the issuance of the Notes and all acts and things necessary to make this
Third Supplemental Indenture a valid, binding and legal obligation of the Company and to constitute a valid agreement of the Company,
in accordance with its terms, have been done and performed.


 


NOW, THEREFORE, for and in consideration of the
premises and the purchase of the Notes by the Holders thereof, it is mutually agreed, for the equal and proportionate benefit of all Holders
of the Notes, as follows:


 


ARTICLE I

TERMS OF THE NOTES


 


Section 1.01     Terms
of the Notes. The following terms relating to the Notes are hereby established:


 


(a)            The
Notes shall constitute a series of Senior Securities having the title “2.050% Notes due 2027.” The Notes shall bear a CUSIP
number of 38173M AC6 and an ISIN number of US38173MAC64.


 


(b)            The
aggregate principal amount of the Notes that may be initially authenticated and delivered under the Indenture (except for Notes authenticated
and delivered upon registration of, transfer of, or in exchange for, or in lieu of, other Notes pursuant to Sections 3.04, 3.05, 3.06,
9.06, 11.07 or 13.05 of the Base Indenture, and except for any Securities that, pursuant to Section 3.03 of the Base Indenture, are
deemed never to have been authenticated and delivered under the Indenture) shall be $350,000,000. Under a Board Resolution, Officers’
Certificate pursuant to Board Resolutions or Future Supplemental Indenture, the Company may from time to time, without the consent of
the Holders of Notes, issue additional Notes (in any such case “Additional Notes”) having the same ranking and the
same interest rate, maturity and other terms as the Notes provided that, if such Additional Notes are not fungible with the Notes (or
any other tranche of Additional Notes) for U.S. federal income tax purposes, then such Additional Notes will have different CUSIP numbers
from the Notes (and any such other tranche of Additional Notes). Any Additional Notes and the existing Notes will constitute a single
series under the Indenture and all references to the relevant Notes herein shall include the Additional Notes unless the context otherwise
requires.


 


(c)            The
entire outstanding principal of the Notes shall be payable on February 15, 2027, unless earlier redeemed or repurchased in accordance
with the provisions of this Third Supplemental Indenture.


 


(d)            The
rate at which the Notes shall bear interest shall be 2.050% per annum. The date from which interest shall accrue on the Notes shall be
August 3, 2021, or the most recent Interest Payment Date to which interest has been paid or provided for; the Interest Payment Dates
for the Notes shall be February 15 and August 15 of each year, commencing February 15, 2022 (if an Interest Payment Date
falls on a day that is not a Business Day, then the applicable interest payment will be made on the next succeeding Business Day and no
additional interest will accrue as a result of such delayed payment); the initial interest period will be the period from and including
August 3, 2021 (or the most recent Interest Payment Date to which interest has been paid or provided for), to, but excluding, the
initial Interest Payment Date, and the subsequent interest periods will be the periods from and including an Interest Payment Date to,
but excluding, the next Interest Payment Date or the Stated Maturity, as the case may be; the interest so payable, and punctually paid
or duly provided for, on any Interest Payment Date, will be paid to the Person in whose name the Note (or one or more Predecessor Securities)
is registered at the close of business on the Regular Record Date for such interest, which shall be February 1 and August 1
(whether or not a Business Day), as the case may be, next preceding such Interest Payment Date. Payment of principal of (and premium,
if any, on) and any such interest on the Notes will be made at the Corporate Trust Office of the Trustee or at such other address as designated
by the Trustee, in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public
and private debts; provided, however, that at the option of the Company payment of interest may be made by (1) check mailed
to the address of the Person entitled thereto as such address shall appear in the Security Register or (2) transfer to an account
maintained by the Person entitled thereto located in the United States; provided, further, however, that so long as the Notes are
registered to Cede & Co., such payment will be made by wire transfer in accordance with the procedures established by The Depository
Trust Company and the Trustee. Interest on the Notes will be computed on the basis of a 360-day year of twelve 30-day months.

Notes shall be initially issuable in global form (each such Note, a “Global Note”). The Global Notes and the Trustee’s
certificate of authentication thereon shall be substantially in the form of Exhibit A to this Third Supplemental Indenture. Each
Global Note shall represent the outstanding Notes as shall be specified therein and each shall provide that it shall represent the aggregate
amount of outstanding Notes from time to time endorsed thereon and that the aggregate amount of outstanding Notes represented thereby
may from time to time be reduced or increased, as appropriate, to reflect exchanges and redemptions. Any endorsement of a Global Note
to reflect the amount of any increase or decrease in the amount of outstanding Notes represented thereby shall be made by the Trustee
or the Security Registrar, in accordance with Sections 2.03 and 3.05 of the Base Indenture.


 


(f)            The
depository for such Global Notes (the “Depository”) shall be The Depository Trust Company. The Security Registrar with
respect to the Global Notes shall be the Trustee.

Notes shall be redeemable pursuant to Section 11.01 of the Base Indenture and as follows:


 


(i)     (A)     The
Notes will be redeemable, in whole or in part, at any time, or from time to time, at the option of the Company, at a Redemption Price
equal to the greater of the following amounts, plus, in each case, accrued and unpaid interest to, but excluding, the Redemption Date:


 


(1)            100%
of the principal amount of the Notes to be redeemed, or


 


(2)            the
sum of the present values of the remaining scheduled payments of principal and interest (exclusive of accrued and unpaid interest to the
Redemption Date) on the Notes to be redeemed through the Par Call Date, discounted to the Redemption Date on a semi-annual basis (assuming
a 360-day year consisting of twelve 30-day months) using the applicable Treasury Rate plus 25 basis points.

in connection with the redemption of the Notes, on any Redemption Date, the following terms shall have the meanings set forth below:


 


“Treasury Rate” means, with respect
to any Redemption Date, the rate per annum equal to the semi-annual equivalent yield-to-maturity of the Comparable Treasury Issue (computed
as of the third Business Day immediately preceding the redemption), assuming a price for the Comparable Treasury Issue (expressed as a

Rate will be determined by the Company.


 


“Comparable Treasury Issue” means the
United States Treasury security selected by the Reference Treasury Dealer as having a maturity comparable to the remaining term of the
Notes to be redeemed (assuming the Notes matured on the applicable Par Call Date) that would be utilized, at the time of selection and

term of the Notes being redeemed.


 


“Comparable Treasury Price” means (1) the
average of the remaining Reference Treasury Dealer Quotations for the Redemption Date, after excluding the highest and lowest Reference
Treasury Dealer Quotations, or (2) if the Quotation Agent obtains fewer than four such Reference Treasury Dealer Quotations, the

that if any of the foregoing or its affiliates shall cease to be a primary U.S. government securities dealer in the United States (a “Primary
Treasury Dealer”), the Company shall select another Primary Treasury Dealer.


 


“Reference Treasury Dealer Quotations”
means, with respect to each Reference Treasury Dealer and any Redemption Date, the average, as determined by the Quotation Agent, 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

Redemption Date.

of redemption shall be given in writing and mailed, first-class postage prepaid, by overnight courier guaranteeing next-day delivery,

redeemed, not less than thirty (30) nor more than sixty (60) days prior to the Redemption Date, at the Holder’s address, facsimile

(iv)            If
the Company elects to redeem only a portion of the Notes, the particular Notes to be redeemed will be selected in accordance with the
applicable procedures of the Depository so long as the Notes are registered to the Depository or its nominee and, if the Notes to be redeemed
are not then held by the Depository, the Trustee shall select the Notes to be redeemed (A) if the Notes are listed on any national
securities exchange, in compliance with the requirements of the principal national securities exchange on which the Notes are listed,
(B) on a pro rata basis to the extent practicable or (C) to the extent that selection on a pro rata basis is not
practicable, by lot or such other similar method the Trustee deems to be fair and appropriate; provided, however, that no such partial
redemption shall reduce the portion of the principal amount of a Note not redeemed to less than $2,000.


 


(v)            Unless
the Company defaults in payment of the Redemption Price, on and after the Redemption Date, interest will cease to accrue on the Notes
called for redemption hereunder.

Notes shall not be subject to any sinking fund pursuant to Section 12.01 of the Base Indenture.

doubt, a pledge of assets pursuant to any secured debt instrument of the Company or its Controlled Subsidiaries shall not be deemed to
be any such sale, transfer, lease, conveyance or disposition) in any one transaction or series of related transactions unless:


 


(i)            the
Company shall be the surviving Person (the “Surviving Person”) or the Surviving Person (if other than the Company) formed

ARTICLE VII

OFFER TO REPURCHASE UPON A CHANGE OF CONTROL REPURCHASE EVENT


 


Section 7.01     Except
as may be provided in a Future Supplemental Indenture, for the benefit of the Holders of the Notes but no other series of Securities under
the Indenture, whether now or hereafter issued and Outstanding, Article Thirteen of the Base Indenture shall be amended by replacing
Sections 13.01 to 13.05 with the following:


 


“SECTION 13.01. Change of Control.


 


If a Change of Control Repurchase Event occurs,
unless the Company shall have exercised its right to redeem the Notes in full, the Company shall make an offer to each Holder of the Notes
to repurchase all or any part (in minimum denominations of $2,000 and integral multiples of $1,000 principal amount in excess thereof)
of that Holder’s Notes at a repurchase price in cash equal to 100% of the aggregate principal amount of Notes repurchased plus any
accrued and unpaid interest on the Notes repurchased to, but not including, the date of purchase. Within 30 days following any Change
of Control Repurchase Event or, at the Company’s option, prior to any Change of Control, but after the public announcement of the
Change of Control, the Company shall mail a notice to each Holder describing the transaction or transactions that constitute or may constitute
the Change of Control Repurchase Event and offering to repurchase Notes on the payment date specified in the notice, which date will be
no earlier than 30 days and no later than 60 days from the date such notice is mailed. The notice shall, if mailed prior to the date of
consummation of the Change of Control, state that the offer to purchase is conditioned on the Change of Control Repurchase Event occurring
on or prior to the payment date specified in the notice. The Company shall comply with the requirements of Rule 14e-1 promulgated
under the Exchange Act and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable
in connection with the repurchase of the Notes as a result of a Change of Control Repurchase Event. To the extent that the provisions
of any securities laws or regulations conflict with this Section 13.01, the Company shall comply with the applicable securities laws
and regulations and shall not be deemed to have breached its obligations under this Section 13.01 by virtue of such conflict.


 


On the Change of Control Repurchase Event payment
date, subject to extension if necessary to comply with the provisions of the Investment Company Act, the Company shall, to the extent
lawful:


 


(i)            accept
for payment all Notes or portions of Notes properly tendered pursuant to its offer;


 


(ii)            deposit
with the Paying Agent an amount equal to the aggregate purchase price in respect of all Notes or portions of Notes properly tendered;
and


 






    11


     


    

 


(iii)            deliver
or cause to be delivered to the Trustee the Notes properly accepted, together with an Officers’ Certificate stating the aggregate
principal amount of Notes being purchased by the Company.


 


The Paying Agent will promptly remit to each Holder
of Notes properly tendered the purchase price for the Notes, and, upon written instruction from the Company, the Trustee will promptly
authenticate and mail (or cause to be transferred by book-entry) to each Holder a new Note equal in principal amount to any unpurchased
portion of any Notes surrendered; provided that each new Note will be in a minimum principal amount of $2,000 or an integral multiple
of $1,000 in excess thereof.


 


If any Repayment Date upon a Change of Control
Repurchase Event falls on a day that is not a Business Day, then the required payment will be made on the next succeeding Business Day
and no additional interest will accrue as a result of such delayed payment.


 


The Company will not be required to make an offer
to repurchase the Notes upon a Change of Control Repurchase Event if a third party makes an offer in respect of the Notes in the manner,
at the time and otherwise in compliance with the requirements for an offer made by the Company and such third party purchases all Notes
properly tendered and not withdrawn under its offer.”

principal sum of _______________ (U.S. $___) on February 15, 2027, and to pay interest thereon from August 3, 2021 or from the
most recent Interest Payment Date to which interest has been paid or duly provided for, semi-annually on February 15 and August 15

2.050% Notes due 2027


 


This Security is one of a duly authorized issue
of Senior Securities of the Company (herein called the “Securities”), issued and to be issued in one or more series under
an Indenture, dated as of October 2, 2020 (herein called the “Base Indenture”, which term shall have the meaning assigned
to it in such instrument), between the Company and U.S. Bank National Association, as Trustee (herein called the “Trustee”,
which term includes any successor trustee under the Base Indenture), and reference is hereby made to the Base Indenture for a statement
of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee, and the Holders of the
Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered, as amended and supplemented by
the Third Supplemental Indenture relating to the Securities, dated as of August 3, 2021, between the Company and the Trustee (herein
called the “Third Supplemental Indenture”; and the Third Supplemental Indenture and the Base Indenture together are herein
called the “Indenture”). In the event of any conflict between the Base Indenture and the Third Supplemental Indenture, the
Third Supplemental Indenture shall govern and control.


 


This Security is one of the series designated on
the face hereof, initially limited in aggregate principal amount to $350,000,000. Under a Board Resolution, Officers’ Certificate
pursuant to Board Resolutions or an indenture supplement, the Company may from time to time, without the consent of the Holders of Securities,
issue additional Securities of this series (in any such case “Additional Securities”) having the same ranking and the same
interest rate, maturity and other terms as the Securities, provided that, if such Additional Securities are not fungible with the
Securities (or any other tranche of Additional Securities) for U.S. federal income tax purposes, then such Additional Securities will
have different CUSIP numbers from the Securities represented hereby (and any such other tranche of Additional Securities). Any Additional
Securities and the existing Securities will constitute a single series under the Indenture and all references to the relevant Securities
herein shall include the Additional Securities unless the context otherwise requires. The aggregate amount of Outstanding Securities represented
hereby may from time to time be reduced or increased, as appropriate, to reflect exchanges and redemptions.


 


The Securities of this series are subject to redemption
in whole or in part at any time or from time to time, at the option of the Company, at a Redemption Price equal to the greater of the
following amounts, plus, in each case, accrued and unpaid interest to, but excluding, the Redemption Date:


 


		(a)	100% of the principal amount of the Securities to be redeemed, or



 


		(b)	the sum of the present values of the remaining scheduled payments of principal and interest (exclusive
of accrued and unpaid interest to the Redemption Date) on the Securities to be redeemed thought the Par Call Date, discounted to the Redemption
Date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) using the applicable Treasury Rate plus 25 basis
points.



 


Notwithstanding the foregoing, at any time on or
after January 15, 2027, the Company may redeem some or all of the Securities at any time or from time to time at a Redemption Price
equal to 100% of the principal amount of the Securities to be redeemed, plus accrued and unpaid interest, if any, to, but excluding, the
Redemption Date.


 


For purposes of calculating the Redemption Price
in connection with the redemption of the Securities, on any Redemption Date, the following terms have the meanings set forth below:


 






    A-5


     


    

 


“Treasury Rate” means, with respect
to any Redemption Date, the rate per annum equal to the semi-annual equivalent yield-to-maturity of the Comparable Treasury Issue (computed
as of the third Business Day immediately preceding the redemption), assuming 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 Redemption Price and the Treasury
Rate will be determined by the Company.


 


“Comparable Treasury Issue” means the
United States Treasury security selected by the Reference Treasury Dealer as having a maturity comparable to the remaining term of the
Securities to be redeemed (assuming the Securities matured on the applicable Par Call Date) that would be utilized, at the time of selection
and in accordance with customary financing practice, in pricing new issues of corporate debt securities of comparable maturity to the
remaining term of the Securities being redeemed.


 


“Comparable Treasury Price” means (1) the
average of the remaining Reference Treasury Dealer Quotations for the Redemption Date, after excluding the highest and lowest Reference
Treasury Dealer Quotations, or (2) if the Quotation Agent obtains fewer than four such Reference Treasury Dealer Quotations, the
average of all such quotations.


 


“Par Call Date” means January 15,
2027, which is the date that is one month prior to the Maturity Date of the Securities.


 


“Quotation Agent” means a Reference
Treasury Dealer selected by the Company.


 


“Reference Treasury Dealer” means each
of (1) a primary U.S. government securities dealer selected by SMBC Nikko Securities America, Inc. and (2) J.P. Morgan
Securities LLC or its affiliates which are primary U.S. government securities dealers, and their respective successors; provided, however,
that if any of the foregoing or its affiliates shall cease to be a primary U.S. government securities dealer in the United States (a “Primary
Treasury Dealer”), the Company shall select another Primary Treasury Dealer.


 


“Reference Treasury Dealer Quotations”
means, with respect to each Reference Treasury Dealer and any Redemption Date, the average, as determined by the Quotation Agent, 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 Quotation Agent by such Reference Treasury Dealer at 3:30 p.m. New York City time on the third Business Day preceding such
Redemption Date.


 


All determinations made by any Reference Treasury
Dealer, including the Quotation Agent, with respect to determining the Redemption Price will be final and binding absent manifest error.


 


Notice of redemption shall be given in writing
and mailed, first-class postage prepaid, by overnight courier guaranteeing next-day delivery, by facsimile or by electronic mail to each
Holder of the Securities to be redeemed, not less than thirty (30) nor more than sixty (60) days prior to the Redemption Date, at the
Holder’s address, facsimile number or email address appearing in the Security Register. All notices of redemption shall contain
the information set forth in Section 11.04 of the Base Indenture.


 


Any exercise of the Company’s option to redeem
the Securities will be done in compliance with the Investment Company Act, to the extent applicable.


 


If the Company elects to redeem only a portion
of the Securities, the particular Securities to be redeemed will be selected in accordance with the applicable procedures of the Depository
so long as the Securities are registered to the Depository or its nominee and, if the Securities to be redeemed are not then held by the
Depository or its nominee, the Trustee shall select the Securities to be redeemed (A) if the Securities are listed on any national
securities exchange, in compliance with the requirements of the principal national securities exchange on which the Securities are listed,
(B) on a pro rata basis to the extent practicable or (C) to the extent that selection on a pro rata basis is not
practicable, by lot or such other similar method the Trustee deems to be fair and appropriate; provided, however, that no such partial
redemption shall reduce the portion of the principal amount of a Security not redeemed to less than $2,000.


 






    A-6


     


    

 


Unless the Company defaults in payment of the Redemption
Price, on and after the Redemption Date, interest will cease to accrue on the Securities called for redemption.


 


Holders will have the right to require the Company
to repurchase their Securities upon the occurrence of a Change of Control Repurchase Event as set forth in the Indenture.


 


The Indenture contains provisions for defeasance
at any time of the entire indebtedness of this Security or certain restrictive covenants and Events of Default with respect to this Security,
in each case upon compliance with certain conditions set forth in the Indenture.


 


If an Event of Default with respect to Securities
of this series shall occur and be continuing (other than Events of Default related to certain events of bankruptcy, insolvency or reorganization
as set forth in the Indenture), 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. In the case of certain events of bankruptcy, insolvency or reorganization described in the Indenture,
100% of the principal of and accrued and unpaid interest on the Securities will automatically become due and payable.


 


The Indenture permits, with certain exceptions
as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders
of the Securities of each series to be affected 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 Securities at the time Outstanding of each series to be affected. The Indenture
also contains provisions permitting the Holders of specified percentages in principal amount of the Securities of each series at the time
Outstanding, on behalf of the Holders of all Securities of such series, to waive compliance by the Company with certain provisions of
the Indenture and certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security
shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration
of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security.


 


As provided in and subject to the provisions of
the Indenture, the Holder of this Security shall not have the right to institute any proceeding with respect to the Indenture or for the
appointment of a receiver or trustee or for any other remedy thereunder, unless such Holder shall have previously given the Trustee written
notice of a continuing Event of Default with respect to the Securities of this series, the Holders of not less than 25% in principal amount
of the Securities of this series at the time Outstanding shall have made written request to the Trustee to institute proceedings in respect
of such Event of Default as Trustee and offered the Trustee indemnity, security or both satisfactory to the Trustee against the costs,
expenses and liabilities to be incurred in compliance with such request, and the Trustee shall not have received from the Holders of a
majority in principal amount of Securities of this series at the time Outstanding a direction inconsistent with such request, and shall
have failed to institute any such proceeding, for sixty (60) days after receipt of such notice, request and offer of indemnity, security
or both. The foregoing shall not apply to any suit instituted by the Holder of this Security for the enforcement of any payment of principal
hereof or any premium or interest hereon on or after the respective due dates expressed herein.


 






    A-7


     


    

 


No reference herein to the Indenture and no provision
of this Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay
the principal of and any premium and interest on this Security at the times, place and rate, and in the coin or currency, herein prescribed.


 


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 of transfer at the office or agency of the Company in any place where the principal of and any premium and interest on
this Security are payable, duly 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 his attorney duly authorized in writing, and thereupon one or more new Securities
of this series and of like tenor, 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 $2,000 and any integral multiples of $1,000 in excess 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 and of like tenor of a different authorized denomination, as requested by the Holder surrendering
the same.


 


No service charge shall be made for any such registration
of transfer or exchange, but the Company or Trustee may require payment of a sum sufficient to cover any tax or other governmental charge
payable in connection therewith.


 


Prior to due presentment of this Security for registration
of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this Security is
registered as the owner hereof for all purposes, whether or not this Security be overdue, and neither the Company, the Trustee nor any
such agent shall be affected by notice to the contrary.


 


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


 


To the extent any provision of this Security conflicts
with the express provisions of the Indenture, the provisions of the Indenture shall govern and be controlling.


 


The Indenture and this Security shall be governed
by and construed in accordance with the laws of the State of New York.
