Re: Initial Public Offering

 

Ladies and Gentlemen:

 

This letter (the “Letter Agreement”)
is being delivered to you in accordance with the Underwriting Agreement (the “Underwriting Agreement”)
entered into by and between ARYA Sciences Acquisition Corp., a Cayman Islands exempted company (the “Company”)
and Jefferies LLC as representative (the “Representative”) of the several underwriters named in Schedule
A thereto (the “Underwriters”), relating to an underwritten initial public offering (the “IPO”)
of the Company’s units (the “Units”), each unit comprised of one Class A ordinary share of the
Company, par value $0.0001 per share (the “Class A Ordinary Shares”), and one-half of one redeemable
warrant, each whole warrant exercisable for one Class A Ordinary Share (each, a “Warrant”). Certain capitalized
terms used herein are defined in paragraph 13 hereof.

 

In order to induce the Company and the
Underwriters to enter into the Underwriting Agreement and to proceed with the IPO, and in recognition of the benefit that such
IPO will confer upon the undersigned, and for other good and valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, the undersigned hereby agrees with the Company as follows:

 

	1.	If the Company solicits approval of its shareholders of a Business Combination, the undersigned
will vote all shares beneficially owned by him or her, whether acquired before, in or after the IPO, in favor of such Business
Combination.

 

	2.	In the event that the Company fails to consummate a Business Combination within the time period
set forth in the Company’s amended and restated memorandum and articles of association, as the same may be further amended
from time to time (the “Charter”), the undersigned will, as promptly as possible, take all necessary
actions to cause the Company to (i) cease all operations except for the purpose of winding up, (ii) as promptly as reasonably possible,
but not more than 10 business days thereafter, redeem the IPO Shares, at a per-share price, payable in cash, equal to the aggregate
amount then on deposit in the Trust Account, including interest earned on the Trust Account not previously released to the Company
(less taxes payable and up to $100,000 of such net interest to pay dissolution expenses), divided by the number of then outstanding
IPO Shares, which redemption will completely extinguish public shareholders’ rights as shareholders (including the right
to receive further liquidation distributions, if any), and (iii) as promptly as reasonably possible following such redemption,
subject to the approval of the Company’s remaining shareholders and the Company’s board of directors, dissolve and
liquidate, subject in the cases of clauses (ii) and (iii) to the Company’s obligations under Cayman Islands law to provide
for claims of creditors and other requirements of applicable law. The undersigned hereby waives any and all right, title, interest
or claim of any kind in or to any distribution of the Trust Account and any remaining net assets of the Company as a result of
such liquidation with respect to the Founder Shares owned by the undersigned. However, if any of the undersigned have acquired
IPO Shares in or after the IPO, they will be entitled to liquidating distributions from the Trust Account with respect to such
IPO Shares in the event that the Company fails to consummate a Business Combination within the time period set forth in the Charter.
The undersigned acknowledges and agrees that there will be no distribution from the Trust Account with respect to any Warrants,
all rights of which will terminate on the Company’s liquidation.

 

    	 	1	 

     

    

 

	3.	The undersigned acknowledges and agrees that prior to entering into a definitive agreement for
a Business Combination with a target business that is affiliated with the undersigned or any other Insiders of the Company or their
affiliates, such transaction must be approved by a majority of the Company’s disinterested independent directors and the
Company must obtain an opinion from an independent investment banking firm, which is a member of the Financial Industry Regulatory
Authority, or an independent accounting firm that such Business Combination is fair to the Company’s unaffiliated shareholders
from a financial point of view.

 

	4.	None of the undersigned, any member of the family of any of the undersigned, or any affiliate of
the undersigned will be entitled to receive and will not accept any compensation or other cash payment prior to, or for services
rendered in order to effectuate, the consummation of the Business Combination; provided that the Company shall be allowed to make
the payments set forth in the Registration Statement adjacent to the caption “Prospectus Summary—The Offering—Limited
payments to insiders.”

 

	5.	(a)	The undersigned agrees that the Founder Shares may
not be transferred, assigned or sold (except to
certain permitted transferees as described in the Registration Statement or herein) (the “Lockup”) until
the earlier to occur of: (1) one year after the completion of a Business Combination or (2) the date following the completion of
the Company’s initial Business Combination on which the Company completes a liquidation, merger, share exchange, reorganization
or other similar transaction that results in all of the Company’s shareholders having the right to exchange their Class A
Ordinary Shares for cash, securities or other property. Notwithstanding the foregoing, if the closing price of the Company’s
Class A Ordinary Shares equals or exceeds $12.00 per share (as adjusted for share splits, share capitalizations, reorganizations,
recapitalizations and the like) for any 20 trading days within any 30-trading day period commencing at least 150 days after the
Company’s initial Business Combination, the Founder Shares will be released from the Lockup.

 

		(b)	The undersigned will not, without the prior written consent of the Representative pursuant to the
Underwriting Agreement, offer, sell, contract to sell, pledge, hedge or otherwise dispose of (or enter into any transaction that
is designed to, or might reasonably be expected to, result in the disposition (whether by actual disposition or effective economic
disposition due to cash settlement or otherwise) by the undersigned or any affiliate of the undersigned or any person in privity
with the undersigned or any affiliate of the undersigned), directly or indirectly, including the filing (or participation in the
filing) of a registration statement with the Securities and Exchange Commission in respect of, or establish or increase a put equivalent
position or liquidate or decrease a call equivalent position within the meaning of Section 16 of the Securities Exchange Act of
1934, as amended, and the rules and regulations of the Securities and Exchange Commission promulgated thereunder with respect to,
any other Units, Class A Ordinary Shares or Warrants of the Company or any securities convertible into, or exercisable, or exchangeable
for, Class A Ordinary Shares or publicly announce an intention to effect any such transaction, for a period of 180 days after the
date of the Underwriting Agreement.

 

    	 	2	 

     

    

 

		(c)	The undersigned agrees that until the Company consummates an initial Business Combination, the
undersigned’s Private Placement Warrants will be subject to the transfer restrictions described in the Private Placement
Warrants Purchase Agreement relating to the undersigned’s Private Placement Warrants.

 

		(d)	Notwithstanding the provisions set forth in paragraphs 5(a) and (c), transfers, assignments and
sales by the undersigned of the Founder Shares, Private Placement Warrants and Class A Ordinary Shares issued or issuable upon
the exercise of the Private Placement Warrants or conversion of the Founder Shares are permitted (i) to the Company’s officers
or directors, any affiliates or family members of any of the Company’s officers or directors, to ARYA Sciences Holdings,
a Cayman Islands exempted limited company (the “Sponsor”), any members or partners of the Sponsor or their affiliates,
or any affiliates of the Sponsor; (ii) in the case of an individual, by gift to a member of the individual’s immediate family
or to a trust, the beneficiary of which is a member of one of the individual’s immediate family, an affiliate of such person
or to a charitable organization; (iii) in the case of an individual, by virtue of laws of descent and distribution upon death of
the individual; (iv) in the case of an individual, pursuant to a qualified domestic relations order; (v) by private sales or transfers
made in connection with the consummation of the Business Combination at prices no greater than the price at which the Founder Shares,
Private Placement Warrants or Class A Ordinary Shares, as applicable, were originally purchased; (vi) by virtue of the Sponsor’s
organizational documents upon liquidation or dissolution of the Sponsor; (vii) to the Company for no value for cancellation in
connection with the consummation of the Business Combination; (viii) in the event of the Company’s liquidation prior to the
completion of a Business Combination; or (ix) in the event of completion of a liquidation, merger, share exchange or other similar
transaction which results in all of the Company’s shareholders having the right to exchange their Class A Ordinary Shares
for cash, securities or other property subsequent to the completion of a Business Combination; provided, however,
that in the case of clauses (i) through (vi) these permitted transferees must enter into a written agreement agreeing to be bound
by the restrictions herein.

 

		(e)	The undersigned acknowledges and agrees that if, in order to consummate any Business Combination,
the holders of Founder Shares or Private Placement Warrants are required to contribute back to the capital of the Company a portion
of any such securities to be cancelled by the Company or transfer any such securities to third parties, the undersigned will contribute
back to the capital of the Company or transfer to such third parties, at no cost, a proportionate number of Founder Shares or Private
Placement Warrants, as applicable, pro rata with the other holders of Founder Shares or Private Placement Warrants, as applicable.

	6.	(a)	In order to minimize potential conflicts of interest that may arise from multiple corporate
                                                                                     affiliations, the undersigned hereby agrees that until the earliest of the Company’s initial Business Combination or

WHEREAS, the Issuer executed and delivered its Indenture (the “Original Indenture”), dated as of July 28, 2006, to the
Trustee to issue from time to time for its lawful purposes debt securities evidencing its unsecured indebtedness. 
 WHEREAS, the
Original Indenture provides that by means of a supplemental indenture, the Issuer may create one or more series of its debt securities and establish the form and terms and conditions thereof. 

WHEREAS, the Issuer intends by this Fifteenth Supplemental Indenture to (i) create a series of debt securities, in an initial

 NOW, THEREFORE IT IS AGREED: 

ARTICLE ONE 

Definitions, Creation, Form and Terms and Conditions of the Debt Securities 

SECTION 1.01. Definitions. Capitalized terms used in this Fifteenth Supplemental Indenture and not otherwise defined shall have
the meanings ascribed to them in the Original Indenture. In addition, the following terms shall have the following meanings to be equally applicable to both the singular and the plural forms of the terms defined: 

“DTC” means The Depository Trust Company. 

“Global Note” means a single fully-registered global note in book-entry form, without coupons, substantially in the form of
Exhibit A attached hereto. 
 “Indenture” means the Original Indenture as supplemented by this Fifteenth Supplemental
Indenture. 

  
 1 

 “Make-Whole Amount” means, in connection with any optional redemption or
accelerated payment of any Note, the excess, if any, of (i) the aggregate present value as of the date of such redemption or accelerated payment of each dollar of principal being redeemed or paid and the amount of interest (exclusive of
interest accrued to the date of redemption or accelerated payment) that would have been payable in respect of each such dollar through June 15, 2028 if such redemption or accelerated payment had been made on June 15, 2028, determined by
discounting, on a semi-annual basis, such principal and interest at the Reinvestment Rate (determined on the third Business Day preceding the date such notice of redemption is given or declaration of acceleration is made) from the respective dates
on which such principal and interest would have been payable if such redemption or accelerated payment had been made on June 15, 2028, over (ii) the aggregate principal amount of the Notes being redeemed or paid. 

“Notes” means the Issuer’s 4.000% Senior Notes due September 15, 2028, a form of which is attached hereto as
Exhibit A. 
 “Redemption Price” means the sum of (i) the principal amount of the Notes being redeemed plus
accrued and unpaid interest thereon to, but excluding, the Redemption Date, and (ii) the Make-Whole Amount, if any, with respect to such Notes; provided, however, that if the Redemption Date is any time on or after June 15, 2028, the
Redemption Price shall mean the principal amount of the Notes being redeemed plus accrued and unpaid interest thereon to, but excluding, the Redemption Date without any payment of a Make-Whole Amount. The Redemption Price shall be calculated by the
Issuer or such other party appointed by the Issuer. 
 “Reinvestment Rate” means 0.200% plus the arithmetic mean of the
yields under the respective heading “Week Ending” published in the most recent Statistical Release under the caption “Treasury Constant Maturities” for the maturity (rounded to the nearest month) corresponding to the remaining
life to maturity (which maturity shall be deemed to be June 15, 2028), as of the payment date of the principal being redeemed or paid. If no maturity exactly corresponds to such maturity, yields for the two published maturities most closely
corresponding to such maturity shall be calculated pursuant to the immediately preceding sentence and the Reinvestment Rate shall be interpolated or extrapolated from such yields on a straight-line basis, rounding in each of such relevant periods to
the nearest month. For the purposes of calculating the Reinvestment Rate, the most recent Statistical Release published prior to the date of determination of the Make-Whole Amount shall be used. 

“Statistical Release” means the statistical release designated “H.15” or any successor publication which is
published weekly by the Federal Reserve System and which establishes yields on actively traded United States government securities adjusted to constant maturities, or, if such statistical release is not published at the time of any determination
under the Indenture, then such other reasonably comparable index which shall be designated by the Issuer. 
 SECTION 1.02.
Creation of the Debt Securities. In accordance with Section 301 of the Original Indenture, the Issuer hereby creates the Notes as a separate series of its debt securities issued pursuant to the Indenture. The Notes shall be issued in an
aggregate principal amount initially limited to $450,000,000. 

  
 2 

 The Issuer may issue, in addition to the Notes originally issued on the date hereof,
additional Notes. The Notes originally issued on the date hereof and any additional Notes originally issued subsequent to the date hereof shall be a single series for all purposes under the Original Indenture. 

SECTION 1.03. Form of the Debt Securities. The Notes will be represented by a single fully-registered global note in book-entry
form, without coupons, registered in the name of the nominee of DTC. The Notes shall be in the form of Exhibit A attached hereto. So long as DTC, or its nominee, is the registered owner of a Global Note, DTC or its nominee, as the case may
be, will be considered the sole owner or holder of the notes represented by such Global Note for all purposes under the Indenture. Ownership of beneficial interests in the Global Note will be shown on, and transfers thereof will be effected only
through, records maintained by DTC (with respect to beneficial interests of participants) or by participants or persons that hold interests through participants (with respect to beneficial interests of beneficial owners). 

SECTION 1.04. Terms and Conditions of the Debt Securities. The Notes shall be governed by all the terms and conditions of the
Original Indenture, as supplemented and modified by this Fifteenth Supplemental Indenture, and in particular, the following provisions shall be terms of the Notes: 

(a) Optional Redemption. The Issuer may redeem the Notes at any time at the option of the Issuer, in whole or from time to time in part,
at a redemption price equal to the Redemption Price. 
 If notice has been given as provided in the Original Indenture and funds for the
redemption of any Notes called for redemption shall have been made available on the Redemption Date referred to in such notice, such Notes will cease to bear interest on the date fixed for such redemption specified in such notice and the only right
of the Holders of the Notes will be to receive payment of the Redemption Price. 
 Notice of any optional redemption of any Notes will be
given to Holders at their addresses, as shown in the Security Register, not more than 60 nor less than 15 days prior to the date fixed for redemption. The notice of redemption will specify, among other items, the Redemption Price and the principal
amount of the Notes held by such Holder to be redeemed. 
 If less than all the Notes are to be redeemed at the option of the Issuer, the
Issuer will notify the Trustee at least 45 days prior to giving notice of redemption (or such shorter period as is satisfactory to the Trustee) of the aggregate principal amount of Notes to be redeemed and their Redemption Date. The Trustee shall
select, in such manner as it shall deem fair and appropriate, no less than 45 days prior to the Redemption Date and in accordance with applicable depositary procedures, the Notes to be redeemed in part. 

(b) Payment of Principal and Interest. Principal and interest payments on interests represented by a Global Note will be made to DTC or
its nominee, as the case may be, as the registered owner of such Global Note. All payments of principal and interest in respect of the Notes will be made by the Issuer in immediately available funds. 

  
 3 

 (c) Applicability of Defeasance or Covenant Defeasance. The provisions of Article 14
of the Original Indenture shall apply to the Notes. 
 (d) Definition of Total Unencumbered Assets. For purposes of the covenant
entitled “Maintenance of Total Unencumbered Assets” in Section 1005 of the Original Indenture, the term “Total Unencumbered Assets” shall be defined, solely with respect to the Notes, as follows: 

“Total Unencumbered Assets” means the sum of (i) those Undepreciated Real Estate Assets not subject to an encumbrance and
(ii) all other assets of the Issuer and its Subsidiaries not subject to an encumbrance determined in accordance with GAAP (but excluding intangibles and accounts receivable); provided, however, that all investments by the Issuer and its
Subsidiaries in unconsolidated joint ventures, unconsolidated limited partnerships, unconsolidated limited liability companies and other unconsolidated entities shall be excluded from the calculation of Total Unencumbered Assets to the extent that
such investments would have otherwise been included. 
 (e) Cross-Acceleration. For purposes of the Event of Default provided for in
Section 501(5) of the Original Indenture, all references to the amount of $5,000,000 shall be increased to $50,000,000; provided, however, that for so long as any of the securities issued pursuant to any supplemental indenture to the Original
Indenture that preceded this Fifteenth Supplemental Indenture are outstanding and provide for this same Event of Default but for a lower amount of such recourse debt, the reference to $50,000,000 in this paragraph is replaced by such lower amount.

 DUKE REALTY LIMITED PARTNERSHIP 

4.000% Senior Notes due 2028 

Duke Realty Limited Partnership, an Indiana limited partnership (the “Issuer,” which term includes any successor under the Indenture
hereinafter referred to), for value received, hereby promises to pay to Cede & Co. or its registered assigns, the principal sum of Four Hundred Fifty Million Dollars on September 15, 2028 (the “Maturity Date”), and to pay
interest thereon from and including September 11, 2018 (or from the most recent interest payment date to which interest has been paid or duly provided for) in U.S. dollars semi-annually in arrears on March 15 and September 15 of each
year, each, an “Interest Payment Date”, commencing on March 15, 2019, and on the Maturity Date, at the rate of 4.000% per annum, until payment of said principal sum has been made or duly provided for. 

 The interest so payable and punctually paid or duly provided for on any Interest Payment
Date and on the Maturity Date will be paid to the Holder in whose name this Note (or one or more predecessor Notes) is registered at the close of business on the “Record Date” for such payment, which will be 15 days (regardless of whether
such day is a Business Day (as defined below)) prior to such payment date or the Maturity Date, as the case may be. Any interest not so punctually paid or duly provided for shall forthwith cease to be payable to the Holder on such Record Date, and
shall be paid to the Holder in whose name this Note (or one or more predecessor Notes) is registered at the close of business on a subsequent Record Date for the payment of such defaulted interest (which shall be not less than five Business Days (as
defined below) prior to the date of the payment of such defaulted interest) established by notice given by mail by or on behalf of the Issuer to the Holders of the Notes not less than 15 days preceding such subsequent Record Date. Interest on this
Note will be computed on the basis of a 360-day year of twelve 30-day months. 

The principal of this Note payable on the Maturity Date will be paid against presentation and surrender of this Note at the office or agency
of the Issuer maintained for that purpose. The Issuer hereby initially designates the Corporate Trust Office of the Trustee at Global Corporate Trust, 2. N. LaSalle Street, Suite 700, Chicago, Illinois 60602 as the office to be maintained by it
where Notes may be presented for payment, registration of transfer, or exchange and where notices or demands to or upon the Issuer in respect of the Notes or the Indenture referred to on the reverse hereof may be served. 

Interest payable on this Note on any Interest Payment Date and on the Maturity Date, as the case may be, will be the amount of interest
accrued from and including the immediately preceding Interest Payment Date (or from and including September 11, 2018, in the case of the initial Interest Payment Date) to but excluding the applicable Interest Payment Date or the Maturity Date,
as the case may be. If any Interest Payment Date or the Maturity Date falls on a day that is not a Business Day (as defined below), the required payment of interest or principal or both, as the case may be, will be made on the next Business Day with
the same force and effect as if it were made on the date such payment was due and no interest will accrue on the amount so payable for the period from and after such Interest Payment Date or the Maturity Date, as the case may be. “Business
Day” means any day, other than a Saturday or a Sunday, on which banking institutions in The City of New York are open for business. 

Payments of principal and interest in respect of this Note will be made by wire transfer of immediately available funds in such coin or
currency of the United States of America as at the time of payment is legal tender for the payment of public and private debts. 
 Reference
is made to the further provisions of this Note set forth on the reverse hereof. Such further provisions shall for all purposes have the same effect as though fully set forth at this place. 

This Note shall not be entitled to the benefits of the Indenture referred to on the reverse hereof or be valid or become obligatory for any
purpose until the certificate of authentication hereon shall have been signed by the Trustee under such Indenture. 

 IN WITNESS WHEREOF, the Issuer has caused this instrument to be signed manually or by
facsimile by its authorized officers.

 [REVERSE OF NOTE] 

DUKE REALTY LIMITED PARTNERSHIP 

4.000% Senior Notes due 2028 

This security is one of a duly authorized issue of debentures, notes, bonds, or other evidences of indebtedness of the Issuer (hereinafter
called the “Securities”) of the series hereinafter specified, all issued or to be issued under and pursuant to an Indenture dated as of July 28, 2006 (hereinafter called the “Indenture”), duly executed and delivered by the
Issuer to The Bank of New York Mellon Trust Company, N.A. (as successor to J.P. Morgan Trust Company, National Association), as Trustee (hereinafter called the “Trustee,” which term includes any successor trustee under the Indenture with
respect to the series of Securities of which this Note is a part), to which the Indenture and all indentures supplemental thereto relating to this security reference is hereby made for a description of the rights, limitations of rights, obligations,
duties, and immunities thereunder of the Trustee, the Issuer, and the Holders of the Securities, and of the terms upon which the Securities are, and are to be, authenticated and delivered. The Securities may be issued in one or more series, which
different series may be issued in various aggregate principal amounts, may mature at different times, may bear interest (if any) at different rates, may be subject to different redemption provisions (if any), and may otherwise vary as provided in
the Indenture or any indenture supplemental thereto. This security is one of a series designated as the 4.000% Senior Notes due 2028 of the Issuer, initially limited in aggregate principal amount to $450,000,000. 

In case an Event of Default with respect to this security shall have occurred and be continuing, the principal hereof and Make-Whole Amount,
if any, may be declared, and upon such declaration shall become, due and payable, in the manner, with the effect, and subject to the conditions provided in the Indenture. 

The Issuer may redeem this security at any time at the option of the Issuer, in whole or in part, at a redemption price equal to the sum of
(i) the principal amount of this security being redeemed plus accrued and unpaid interest thereon to, but excluding, the Redemption Date, and (ii) the Make-Whole Amount, if any, with respect to this security (the “Redemption
Price”); provided, however, that if the Redemption Date is any time on or after June 15, 2028, the Redemption Price shall mean the principal amount of the Notes being redeemed plus accrued and unpaid interest thereon to, but excluding, the
Redemption Date without any payment of a Make-Whole Amount. Notice of any optional redemption of any Securities will be given to Holders at their addresses, as shown in the Security Register, not more than 60 days nor less than 15 days prior to the
date fixed for redemption. The notice of redemption will specify, among other items, the Redemption Price and the principal amount of the Securities held by such Holder to be redeemed. 

The Indenture contains provisions permitting the Issuer and the Trustee, with the consent of the Holders of not less than a majority of the
aggregate principal amount of the Securities at the time outstanding of all series to be affected (voting as one class), evidenced as provided in the Indenture, to execute supplemental indentures adding any provisions to or changing in any manner or
eliminating any of the provisions of the Indenture or of any supplemental indenture or modifying in any manner the rights of the Holders of the Securities of each series; provided, however, that no such supplemental indenture shall, without the
consent of the Holder of each Security so affected, (i) change the Stated Maturity of the principal of (or premium, if any, on) or any installment of principal of or 

 
interest on, any Security, or reduce the principal amount thereof or the rate or amount of interest thereon or any premium payable upon the redemption thereof, or adversely affect any right of
repayment at the option of the Holder of any Security, or change any Place of Payment where, or the currency or currencies, currency unit or units or composite currency or currencies in which, any Security or any premium or the interest thereon is
payable, or impair the right to institute suit for the enforcement of any such payment on or after the Stated Maturity thereof, or (ii) reduce the aforesaid percentage of Securities, the Holders of which are required to consent to any such
supplemental indenture, or (iii) reduce the percentage of Securities, the Holders of which are required to consent to any waiver of compliance with certain provisions of the Indenture or any waiver of certain defaults thereunder. It is also
provided in the Indenture that, with respect to certain defaults or Events of Default regarding the Securities of any series, the Holders of a majority in aggregate principal amount outstanding of the Securities of such series (or, in the case of
certain defaults or Events of Default, all series of Securities) may on behalf of the Holders of all the Securities of such series (or all of the Securities, as the case may be) waive any such past default or Event of Default and its consequences,
prior to any declaration accelerating the maturity of such Securities, or, subject to certain conditions, may rescind a declaration of acceleration and its consequences with respect to such Securities. Any such consent or waiver by the Holder of
this security (unless revoked as provided in the Indenture) shall be conclusive and binding upon such Holder and upon all future Holders and owners of the security and any securities that may be issued in exchange or substitution herefor,
irrespective of whether or not any notation thereof is made upon this security or such other securities. 
 No reference herein to the
Indenture and no provision of this security or of the Indenture shall alter or impair the obligation of the Issuer, which is absolute and unconditional, to pay the principal of and any Make-Whole Amount and interest on this security in the manner,
at the respective times, at the rate and in the coin or currency herein prescribed. 
 This security is issuable only in registered form
without coupons in denominations of $2,000 principal amount and integral multiples of $1,000 in excess thereof. Securities may be exchanged for a like aggregate principal amount of securities of this series of other authorized denominations at the
office or agency of the Issuer, in the manner and subject to the limitations provided in the Indenture, but without the payment of any service charge except for any tax or other governmental charge imposed in connection therewith. 

Upon due presentment for registration of transfer of Securities at the office or agency of the Issuer, one or more new Securities of the same
series of authorized denominations in an equal aggregate principal amount will be issued to the transferee in exchange therefor, subject to the limitations provided in the Indenture, without charge except for any tax or other governmental charge
imposed in connection therewith. 
 The Issuer, the Trustee or any authorized agent of the Issuer or the Trustee may deem and treat the
Person in whose name this security is registered as the absolute owner of this security (whether or not this security shall be overdue and notwithstanding any notation of ownership or other writing hereon), for the purpose of receiving payment of,
or on account of, the principal hereof and Make-Whole Amount, if any, and subject to the provisions on the face hereof, interest hereon, and for all other purposes, and neither the Issuer nor the Trustee nor any authorized agent of the Issuer or the
Trustee shall be affected by any notice to the contrary. 

 The Indenture and each Security shall be deemed to be a contract under the laws of the State
of New York, and for all purposes shall be construed in accordance with the laws of such state, except as may otherwise be required by mandatory provisions of law. 

Capitalized terms used herein which are not otherwise defined shall have the respective meanings assigned to them in the Indenture and all
indentures supplemental thereto relating to this security.
