 Exhibit 10.6 

DT MIDSTREAM, INC. 

Annual Incentive Plan 

Purpose 
 DT Midstream, Inc.
(“Midstream”) has established the DT Midstream, Inc. Annual Incentive Plan (“Plan”) for the purpose of providing incentives for eligible employees of Midstream to contribute to the success of Midstream by achieving pre-established financial and strategic goals for Midstream and individual performance goals for the employee. 

Definitions 
 “Award”
means, with respect to a Plan Year, the applicable percentages (e.g., target, minimum and maximum percentages), Performance Measures, and weights and performance levels for each Performance Measure as established by the Committee in writing and
communicated to each Participant for that Plan Year. 
 “Board” means the Board of Directors of DT Midstream, Inc. 

“Change in Control” for purposes of the Plan will have occurred if any of the following events occurs: 

 

	 	1.	 The consummation of a transaction in which Midstream is merged, consolidated or reorganized into or with
another corporation or other legal person (the “Surviving Entity”), and as a result of the transaction less than 50% of the combined voting power of the then-outstanding securities entitled to vote generally in the election of directors
(“Voting Stock”) of the Surviving Entity immediately after the transaction is held in the aggregate by the holders of Voting Stock of Midstream immediately prior to the transaction; 

 

	 	2.	 The consummation of a sale or transfer in which Midstream sells or otherwise transfers all or substantially all
of its assets to another corporation or other legal person (the “Acquiring Entity”), and as a result of the sale or transfer less than 50% of the combined voting power of the then-outstanding Voting Stock of the Acquiring Entity
immediately after the sale or transfer is held in the aggregate (directly or through ownership of Voting Stock of Midstream) by the holders of Voting Stock of Midstream immediately prior to the sale or transfer. However, a sale or transfer described
in this Section will not constitute a Change in Control if the sale or transfer is pursuant to a spin-off type of transaction (directly or indirectly) of the Company’s assets to the Company’s
shareholders; 

  

	 	3.	 The approval by the shareholders of Midstream of a complete liquidation or dissolution of Midstream;

  

	 	4.	 Any “person” (as such term is used in Sections 13(d) and 14(d) of the Exchange Act, other than
(A) a trustee or other fiduciary holding securities under an employee benefit plan of the Company or any Affiliate, or (B) any corporation owned, directly or indirectly, by the shareholders of the Company

in substantially the same proportions as their ownership of the Common Stock) becomes the “beneficial owner” (as defined in Rule 13d-3 of the
Exchange Act), directly or indirectly, of securities of the Company representing thirty percent (30%) or more of the total voting power represented by the Company’s then outstanding voting securities; 

 

	 	5.	 A change in the composition of the Board occurring within any consecutive twelve month period, as a result of
which fewer than a majority of the directors are Incumbent Directors. “Incumbent Directors” means directors who either (i) are Directors or Directors-Elect as of the first date the Common Stock is listed on any established stock
exchange, or (ii) are elected, or nominated for election, to the Board with the affirmative votes of at least a majority of the Incumbent Directors at the time of the election or nomination (but will not include an individual whose election or
nomination is in connection with an actual or threatened proxy contest relating to the election of directors to the Company). However, a change in the composition of the Board described in this Section will not constitute a Change in Control if the
change in the composition of the Board is pursuant to a spin-off type of transaction (directly or indirectly) of the Company’s Voting Stock or assets to the Company’s shareholders.

 “Change in Control Award” means an Award for a Plan Year ending before a Change in Control occurs or an Award for a Plan Year
in which a Change in Control occurs. 
 “Committee” means the committee of the Board responsible for determining and approving compensation for
Midstream’s Chief Executive Officer and for recommending to the Board compensation for all other Midstream executive officers. If required by the listing rules of any domestic stock exchange on which Midstream stock is listed, the Committee
will be composed solely of individuals who are “Non-Employee Directors” as that term is used in Rule 16b-3 under the Securities Exchange Act of 1934 and who
satisfy any other applicable requirements under the listing exchange’s rules. 
 “Disability” means a Participant’s eligibility to
receive benefits under a long-term disability plan sponsored by Midstream. 
 “Participant” means any employee of Midstream selected by the
Committee to receive an Award for that Plan Year. 
 “Performance Measure” is an objective determined by the Committee (in its discretion) to be
applicable to a Participant with respect to an Award. The Performance Measures may differ from Participant to Participant and from Award to Award. Any criteria used may be measured, as applicable, in absolute or relative terms (including passage of
time and/or against another company or companies), on a per share basis, against the performance of Midstream as a whole or any division of Midstream, and on a pre-tax or
after-tax basis. A Performance Measure measures performance for a Plan Year. Examples of Performance Measures include: 

  
 DT Midstream, Inc. Annual

	 	1.	 growth based on increasing sales or profitability of one or more business units; 

 

	 	2.	 compression reliability; 

 

	 	3.	 earnings per share growth; 

 

	 	4.	 employee satisfaction; 

 

	 	5.	 return on equity;

	 	7.	 cash flow 

  

	 	8.	 earnings growth; 

  

	 	9.	 diversity; 

  

	 	10.	 safety; 

  

	 	11.	 production cost; or 

  

	 	12.	 other measures as may be selected by the Committee. 

“Plan Year” means the calendar year. 

“Retirement” means a Participant’s termination of employment with Midstream (a) at or after age 55 with at least 10 years of service with
Midstream or (b) at or after age 65. For purposes of determining a Participant’s eligibility for Retirement, service with DTE Energy Company and related employers will be recognized to the extent required by the Employee Matters Agreement
between Midstream and DTE Energy Company. 
 Annual Award Procedures 

For each Plan Year, the Committee will establish and report to the Board the specific criteria for eligibility, the type and timing of Awards and the manner
of payment of Awards, the Performance Measures and related weights to be used in computing Award amounts, and the performance levels for each Performance Measure. The Committee will then notify each Participant of the terms of the Participant’s
Award for that Plan Year. 
 Award Payment 

Awards for a Plan Year are not payable until the Committee has certified that the Performance Measures and levels entitling a Participant to payment have been
satisfied. The Committee reserves the right to reduce (by up to 100%) the amount payable under any Award or to cancel any outstanding Award if, in the Committee’s sole discretion, the Committee determines that the reduction or cancellation is
in Midstream’s best interests. 
 The Committee, or the Committee’s delegate, will establish procedures for calculating each Participant’s
Award for a Plan Year. The maximum amount that may be paid to any Participant under an Award for a single Plan Year is $6,000,000. 

  
 DT Midstream, Inc. Annual
Incentive Plan – Page 3 of 6 

 The payment, if any, under an Award will be made as soon as practicable following certification by the
Committee, but in no event later than the end of the Plan Year following the Plan Year for which the Award was made.     

Forfeiture of Award Payment 
 A
Participant whose employment with Midstream terminates before payment is made under an Award for a Plan Year forfeits any Award to which the Participant may have been entitled for that Plan Year. However, if the Participant’s employment
terminates during a Plan Year because of the Participant’s Retirement, Disability, or death, the Participant (or the Participant’s beneficiary, in the event of the Participant’s death) will be eligible to receive: 

 

	 	1.	 payment of any Award for a completed Plan Year not yet paid as of the Participant’s termination date; and

  

	 	2.	 a pro-rata portion of the Award the Participant would have received for
the Plan Year in which the Participant’s employment terminated. 

 The amount paid under (2), above, will be: 

 

	 	•	 	 the amount of the Award that would have been payable if the Participant’s employment had not terminated,
based on actual attainment of applicable Performance Measures as certified by the Committee, times 

  

	 	•	 	 a fraction, the numerator of which is the number of days in the Plan Year to which the Award relates before the
Participant’s termination date, and the denominator of which is 365.     

 The
pro-rata portion of the Award is subject to reduction in the Committee’s sole discretion based on the Participant’s individual performance during the Participant’s period of employment during
the Plan Year of termination. 
 Any payment of an Award made to a Participant whose employment terminated because of the Participant’s Retirement,
Disability, or death will be made at the time the payment would have been made if the Participant’s employment had not terminated. 

Beneficiary 
 Any Award payable
after the Participant’s death will be paid: 
  

	 	1.	 to the beneficiary designated by the Participant for any group life insurance provided by Midstream on the
Participant’s life; or 

  

	 	2.	 if the Participant has not designated a beneficiary for any group life insurance provided by Midstream, to the
Participant’s estate. 

 Change in Control Awards 

This section supersedes any conflicting provision of the Plan.     

  
 DT Midstream, Inc. Annual
Incentive Plan – Page 4 of 6 

 After a Change in Control occurs, no certification of Performance Measures and levels is required for any
Change in Control Award. The amount of the Change in Control Award earned is the greater of the amount that would have been payable on attainment of: 
  

	 	1.	 target performance level for each Performance Measure; or 

 

	 	2.	 actual performance level for each Performance Measure, 

using performance through the date the Change in Control occurred for purposes of determining actual levels of performance.     

No Change in Control Award may be reduced by the Committee, modified or canceled.     

The Plan may not be terminated or substantially modified in a way that adversely affects any Change in Control Award without the affected Participant’s
written consent. 
 Administration and Amendment 

The Committee administers the Plan. The Committee has the authority to interpret the provisions of the Plan and prescribe any regulations relating to its
administration. The decisions of the Committee with respect to the administration of the Plan are conclusive, subject to any limitations on the Committee’s action imposed by the terms of the Plan or any Award. 

The Board reserves the right to amend, suspend or terminate the Plan at any time. 

Funding Status 
 Benefits under the
Plan are payable solely from the general assets of Midstream and remain unfunded and unsecured (under the Internal Revenue Code and Title I of the Employee Retirement Income Security Act of 1974, as amended) during the entire period of the
Plan’s existence. Each Participant and the Participant’s beneficiary are merely general creditors of Midstream and the obligations of Midstream under the Plan are contractual and are not funded or secured in any way. However, nothing in
the Plan precludes Midstream from segregating assets that are intended to be a source of payment of benefits under the Plan, as long as those assets remain subject to the general creditors of Midstream. 

Additional Provisions 
 Non-Alienability and Non-Transferability 
 No Participant and no beneficiary
of a Participant may alienate, assign, transfer, pledge, or encumber the Participant’s or beneficiary’s right to payment of any benefit under the Plan or subject the right to payment of any benefit under the Plan to execution, attachment,
or any similar process. A Participant’s account cannot be subject in any manner to alienation, sale, transfer, assignment, pledge, encumbrance, charge, garnishment, execution or levy of any kind, whether voluntary or involuntary,

  
 DT Midstream, Inc. Annual
Incentive Plan – Page 5 of 6 

 
including but not limited to any liability which is for alimony or other payments for the support of a spouse or former spouse, or for any other relative of the Participant. Any attempted
assignment, pledge, levy or similar process is null and void and without effect. 
 Governing Law 

The Plan is governed by the laws of the State of Delaware, except for its
choice-of-law provisions. 
 Effect on Employment 

Participation in the Plan does not guarantee a Participant continued employment with Midstream. 

Participation in the Plan does not affect a Participant’s eligibility to participate in any other benefit or incentive plan of Midstream. Treatment of
any income realized as a result of the payment of any Award under the Plan for purposes of any Midstream-sponsored employee retirement benefit plan, insurance, or other employee benefit program will be governed by the terms of the other plan or
program. 
 Acceptance of Award 
 By accepting an Award
under the Plan, a Participant and the Participant’s successor in interest or personal representative is conclusively deemed to have indicated acceptance or ratification of, and consent to, any action taken under the Plan by the Committee or its
delegate.

Payment
Account: On the Closing Date, the Trustee shall establish (and shall promptly notify the Company of the establishment of such
account, including the relevant account numbers and other relevant identifying details) and, until the Notes and all accounts due in respect
thereof have been paid in full, the Trustee shall continue to maintain the special purpose non-interest bearing trust account established
pursuant to the Second Supplemental Indenture (the “Payment Account”) into which all payments required to be made by
the Company under or with respect to the Notes shall be deposited. The Company agrees that the Payment Account shall continue to be maintained
in the name of the Trustee and under its sole dominion and control (acting on behalf of the Holders) and used solely to make payments
of principal, interest and other amounts from time to time due and owing on, or with respect to, the Notes. No funds contained in the
Payment Account shall be used for any other purpose or in any manner not expressly provided for herein nor shall the Company or any other
Person have an interest therein or amounts on deposit therein. All amounts on deposit in the Payment Account on any Interest Payment Date
after the Trustee has paid all amounts due and owing to the holders of the Notes as of such Interest Payment Date shall be retained in
the Payment Account and used by the Trustee to pay any amounts due and owing to the Holders on the next succeeding Interest Payment Date.

Denomination: The Notes shall be issuable in whole in the registered form of one or more Global Notes (without coupons), in
minimum denominations of U.S.$1,000 and integral multiples thereof, and shall be transferable in integral multiples of U.S.$1,000 and
integral multiples thereof and the Depository for such Global Notes shall be The Depository Trust Company, New York, New York.

 

Guarantee:
The Notes shall have the benefit of the Guarantee in the manner provided in Article 3 of this Second Supplemental Indenture.

The Notes can be issued without the requirement that they have any rating from a nationally recognized statistical rating organization.

 

Optional
Early Redemption. The Notes are subject to redemption at the Company’s option prior to the Par Call Date in whole at
any time, or in part from time to time, at a redemption price equal to the greater of (A) 100% of the principal amount of such Notes
and (B) the sum of the present values, calculated as of the redemption date, of the remaining scheduled payments of principal and
interest thereon (exclusive of interest accrued to the redemption date) (calculated at a rate of 3.125% per annum until (i) the interest
period immediately following the Women in Leadership Positions Interest Rate Step Up Date and prior to the Industrial Water Withdrawal
Intensity Interest Rate Step Up Date, during which period the interest rate shall be deemed to be the Women in Leadership Positions Subsequent
Rate of Interest, as applicable, and (ii) the interest period immediately following the Industrial Water Withdrawal Intensity Interest
Rate Step Up Date, at which point the interest rate shall be deemed to be the Industrial Water Withdrawal Intensity Subsequent Rate of
Interest, as applicable, as set forth in Section 2.01(vi)), as if the bonds were redeemed on the Par Call Date, discounted to the
redemption date on an annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus 30 basis points,
plus in each case, any accrued and unpaid interest and Additional Amounts, if any, on such notes to the redemption date, as calculated
by the Independent Investment Banker. At any time on or after the Par Call Date, the Company will have the right to redeem the Notes,
in whole or in part and from time to time, at a redemption price equal to 100% of the principal amount of the Notes being redeemed plus
accrued and unpaid interest on the principal amount of the Notes being redeemed to such redemption date.

 

Early
Redemption Solely for Tax Reasons. If as a result of any change in or amendment to the laws or treaties (or any rules or
regulations thereunder) of any Taxing Jurisdiction, or any amendment to or change in an official interpretation, administration or application
of such laws, treaties, rules, or regulations (including a holding by a court of competent jurisdiction), which change or amendment or
change in official position becomes effective on or after the issue date, or, with respect to a successor, after the date a successor
assumes the obligations under the Notes or the note guarantees, the Company or Suzano or a successor have or will become obligated to
pay Additional Amounts in excess of the Additional Amounts that the Company or Suzano would be obligated to pay if payments were subject
to withholding or deduction at a rate of 15% (or at a rate of 25% in case the holder of the Notes is resident in a tax haven jurisdiction,
i.e., countries which do not impose any income tax or which impose it at a maximum rate lower than 20% or where the laws impose restrictions
on the disclosure of ownership composition or securities ownership) as a result of the taxes, duties, assessments and other governmental
charges described above (the “Minimum Withholding Level”), then the Company may, at its option, redeem all, but not
less than all, of the Notes, at a redemption price equal to 100% of their principal amount, together with interest and Additional Amounts
accrued to the date fixed for redemption, upon publication of irrevocable notice not less than 15 days nor more than 90 days prior to
the date fixed for redemption. No notice of such redemption may be given earlier than 90 days prior to the earliest date on which the
Company would, but for such redemption, be obligated to pay the Additional Amounts above the Minimum Withholding Level, were a payment
then due. The Company shall not have the right to so redeem the Notes in the event it becomes obliged to pay Additional Amounts which
are less than the Additional Amounts payable at the Minimum Withholding Level. Notwithstanding the foregoing, the Company shall not have
the right to so redeem the Notes unless: (i) it has taken measures it considers reasonable to avoid the obligation to pay Additional
Amounts; and (ii) it has complied with all applicable regulations to legally effect such redemption; provided, however, that for
this purpose reasonable measures shall not include any change in the Company’s, Suzano’s or any successor’s jurisdiction
of incorporation or organization or location of each of their principal executive or registered office.

 

    	 	7	 

     

    

 

In the event that the Company elects to so redeem
the Notes, it will deliver to the Trustee: (i) a certificate, signed in the name of the Company by two of its directors or by its
attorney in fact in accordance with its articles of association, stating that the Company is entitled to redeem the Notes pursuant to
their terms and setting forth a statement of facts showing that the condition or conditions precedent to the right of the Company to so
redeem have occurred or been satisfied; and (ii) an Opinion of Counsel (as provided for in the Indenture) to the effect that the
Issuer has or will become obligated to pay Additional Amounts in excess of the Additional Amounts payable at the Minimum Withholding Level
as a result of the change or amendment and that all governmental approvals necessary for the Issuer to effect the redemption have been
obtained and are in full force and effect.

 

Conversion:
The Notes will not be convertible into, or exchangeable for, any other securities.

 

Defeasance:
The provisions of Sections 13.01, 13.02 and 13.03 of the Base Indenture shall apply to the Notes.

 

Covenants:
Except as set forth in Section 2.05, the Notes will be subject to the covenants set forth in Article 10 of the Base Indenture.

judicial or extrajudicial or other similar arrangement with its creditors, or appoints or applies for the appointment of an administrator,

its Debt or any part of it;

 

(h)            the
Guarantee ceases to be in full force and effect, other than in accordance with the terms of this Indenture, or Suzano denies or disaffirms
its obligations under the Guarantee; and

 

(i)            Any
event occurs that under the laws of any relevant jurisdiction has substantially the same effect as any of the events referred to in any
of paragraphs (e), (f) or (g) of this ‎Section 5.01.”

Reverse of Global Security

 

This Security is one of a duly
authorized issue of securities of the Company (herein called the “Securities”), issued and to be issued in one or more
series under an Indenture, dated as of January 24, 2020, as supplemented with respect to the Securities (herein called the “Indenture”
which term shall have the meaning assigned to it in such instrument), between the Company, the Guarantor and Deutsche Bank Trust Company
Americas, as Trustee (herein called the “Trustee,” which term includes any other successor trustee under the Indenture),
and reference is hereby made to the 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. This Security is one of the series designated on the face hereof.

 

Prior to October 15, 2031
(the “Par Call Date”), the Company may redeem the Securities in whole at any time, or in part from time to time, at
a redemption price based on a “make-whole” premium, plus accrued and unpaid interest, if any, to the redemption date. At any
time on or after the Par Call Date, we may redeem the Securities, in whole or in part at a redemption price equal to 100% of the principal
amount of the Securities being redeemed plus accrued and unpaid interest on the principal amount of the Securities being redeemed to such
redemption date. For purposes of optional redemption, interest will be calculated after the Interest Rate Step Up Date at the Subsequent
Rate of Interest, unless the Sustainability Performance Target has been satisfied and the Issuer has provided Satisfaction Notification
to the Trustee in writing on the Notification Date.

 

The Company may redeem the Securities,
in whole but not in part, at 100% of its principal amount plus accrued and unpaid interest and Additional Amounts (as defined below),
if any, at any time upon the occurrence of specified events relating to Brazilian, Austrian or other relevant jurisdictions’ tax
laws.

 

Notice of redemption will be
given by mail to Holders of Securities of this series, not less than 15 days nor more than 60 days prior to the date fixed for redemption,
all as provided in the Indenture.  Such notice may at the Company’s option be subject to the satisfaction of one or more
conditions precedent, and it may be rescinded or the applicable redemption date delayed in the event that any or all such conditions shall
not have been satisfied by the applicable redemption date.  Any conditions precedent shall be described in such notice.

 

In the event of redemption of
this Security in part only, a new Security or Securities of this series and of like tenor for the unredeemed portion hereof will be issued
in the name of the Holder hereof upon the cancellation hereof.

 

The Indenture contains provisions
for defeasance at any time of the entire indebtedness on 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, 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.

 

    

     

    

 

If any deduction or withholding
for any present or future taxes, assessments or other governmental charges of Brazil or Austria (or any political subdivision or taxing
authority thereof or therein) shall at any time be required by Brazil or Austria (or any such political subdivision or taxing authority)
in respect of any amounts to be paid by the Company under the Securities, the Company will pay to the Holder of this Security such additional
amounts as may be necessary in order that the net amounts paid to such Holder of such Security who, with respect to any such tax, assessment
or other governmental charge, is not resident in Brazil or Austria, after such deduction or withholding, shall be not less than the amounts
specified in such Security to which such Holder is entitled (“Additional Amounts”); provided, however, that the Company
shall not be required to make any payment of Additional Amounts for or on account of:

 

any tax, assessment
or other governmental charge which would not have been imposed but for (i) the existence of any present or former connection between
such Holder or the beneficial owner of the Security of such series (or between a fiduciary, settler, beneficiary, member or shareholder
of, or possessor of a power over, such Holder or beneficial owner, if such Holder or beneficial owner is an estate, trust, partnership
or corporation) and Brazil or Austria or any political subdivision or territory or possession thereof or area subject to its jurisdiction
other than the mere holding of a Security or receipt of payment in respect thereto, including, without limitation, such Holder or beneficial
owner (or such fiduciary, settler, beneficiary, member, shareholder or possessor) being or having been a citizen or resident thereof or
being or having been present or engaged in trade or business therein or having or having had a permanent establishment therein or (ii) the
presentation of a Security of such series (where presentation is required) for payment on a date more than 30 days after the date on which
such payment became due and payable or the date on which payment thereof is duly provided for, whichever occurs later;

 

any estate, inheritance,
gift, sale, transfer, personal property or similar tax, assessment or other governmental charge;

 

any amount required
to be deducted or withheld by any Paying Agent from a payment on or in respect of the Security, if such payment can be made without such
deduction or withholding by any other Paying Agent and we duly provide for such other Paying Agent to make such payment;

 

withholding for
any taxes, duties, assessments or other governmental charges that are payable otherwise than by deduction or withholding from payments
on the Security;

 

any tax, assessment
or other governmental charge that is imposed or withheld by reason of the failure to comply by the Holder or the beneficial owner of the
Security of such series with a request of the Company addressed to the Holder (i) to provide information concerning the nationality,
residence or identity of the Holder or such beneficial owner or (ii) to make any declaration or other similar claim or satisfy any
information or reporting requirements, which, in the case of (i) or (ii), is required or imposed by a statute, treaty, regulation
or administrative practice of Brazil or Austria as a precondition to exemption from all or part of such tax, assessment or other governmental
charge;

 

(f)            where
the Holder would have been able to avoid the tax, levy, deduction or other governmental charge by taking reasonable measures available
to such Holder; or

 

(g)            any
combination of items (a), (b), (c), (d), (e) and (f) above;

 

nor shall Additional Amounts be paid with respect
to any payment in respect of any Security to any Holder or beneficial owner who is a fiduciary or partnership or other than the sole beneficial
owner of such payment to the extent such payment would be required by the laws of Brazil or Austria (or any political subdivision or taxing
authority thereof or therein) to be included in the income for tax purposes of a beneficiary or settlor with respect to such fiduciary
or a member of such partnership or a beneficial owner who would not have been entitled to such Additional Amounts had it been the Holder
or beneficial owner, as the case may be, of such Security.

 

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 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 hereof or in lieu hereof, whether or not notation of such consent or waiver is made
upon this Security.

 

    

     

    

 

As set forth in, and subject
to, the provisions of the Indenture, no Holder of any Security of this series will have any right to institute any proceeding with respect
to the Indenture, this Security 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 the Securities of this series, the Holders of not less than 25% in principal amount of
the Outstanding Securities of this series shall have made written request, and offered indemnity or security satisfactory to the Trustee
to institute such proceeding as trustee, and the Trustee shall not have received from the Holders of a majority in principal of the Outstanding
Securities of this series a direction inconsistent with such request and 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 (and premium, if any), interest or any Additional Amount on this Security on or after the respective due dates expressed herein.

 

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 or to convert or exchange this Security as provided in the Indenture.

 

The Securities of this series
are issuable only in registered form without coupons in denominations of U.S.$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 and of like tenor of a different authorized denomination, as requested by the Holder surrendering
the same. 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.

 

No service charge shall be made
for any such registration of transfer or exchange, but the Company and the 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 or the Trustee nor any such agent shall be affected by notice to the contrary.

 

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

 

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