reverse hereof), for value received, hereby promises to pay to Cede & Co. or its registered assigns, the principal sum of FIVE
HUNDRED MILLION DOLLARS on May 15, 2027 (except to the extent redeemed or repaid prior to that date). The Company shall pay interest
on such principal amount at the rate of 5.375% per annum, until payment of such principal amount has been made or duly provided
for, semi-annually in arrears on May 15 and November 15 of each year (each, an “Interest Payment Date”). Interest shall
be payable on each Interest Payment Date, commencing on November 15, 2017, and at the stated maturity or earlier redemption or
repayment (the “Maturity Date”). If the Company shall default in the payment of interest due on any Interest Payment
Date, then this Note shall bear interest from the next preceding Interest Payment Date to which interest has been paid, or, if
no interest has been paid on this Note, from May 23, 2017 (the “Original Issue Date”).


 


Interest on this Note shall accrue from
the Original Issue Date until the principal amount is paid or duly provided for. Interest (including payments for partial periods)
shall be computed


 




     


     


    

 


on the basis of a 360-day year of twelve 30-day
months. Interest payable on this Note on any Interest Payment Date or the Maturity Date shall include interest accrued from, and
including, the preceding Interest Payment Date in respect of which interest has been paid or duly provided for (or from, and including,
the Original Issue Date, if no interest has been paid or duly provided for) to, but excluding, such Interest Payment Date or the
Maturity Date, as the case may be. If the Maturity Date or any Interest Payment Date falls on a day which is not a Business Day
(as defined below), principal of or interest payable with respect to the Maturity Date or such Interest Payment Date shall be paid
on the succeeding Business Day, and no additional interest shall accrue as a result of that postponement. The interest so payable,
and punctually paid or duly provided for, on any Interest Payment Date shall be paid to the person in whose name this Note (or
one or more predecessor Notes evidencing all or a portion of the same debt as this Note) is registered at the close of business
on the regular record date for such Interest Payment Date, whether or not a Business Day. The regular record date shall be the
close of business on May 1 and November 1 preceding an Interest Payment Date. “Business Day” means any weekday that
is not a legal holiday in New York, New York or Wilmington, Delaware and that is not a day on which banking institutions in those
cities are authorized or required by law or regulation to be closed.


 


The principal of and interest on this Note
are payable in immediately available funds in such coin or currency of the United States as at the time of payment is legal tender
for payment of public and private debts, at the office or agency of the Company designated as provided in the Indenture. However,
interest may be paid, at the option of the Company, by check mailed to the person entitled thereto at his address last appearing
on the registry books of the Company relating to the Notes. Notwithstanding the preceding sentence, payments of principal of and

THE CHEMOURS
COMPANY

5.375% SENIOR NOTE DUE 2027


 


SECTION 1. General. This Note is
one of a duly authorized series of Securities of the Company unlimited in aggregate principal amount (herein called the “Notes”)
issued and to be issued under an Indenture dated as of May 23, 2017 (herein called the “Base Indenture”),
between the Company and U.S. Bank National Association, as Trustee (herein called the “Trustee,” which term includes
any successor trustee under the Indenture, as supplemented by a First Supplemental Indenture dated as of May 23, 2017 (the “First
Supplemental Indenture” and, together with the Base Indenture, the “Indenture”), to which Indenture
and all indentures supplemental thereto reference is hereby made for a statement of the respective rights thereunder of the Company,
the Trustee, and the holders of the Notes, and the terms upon which the Notes are, and are to be, authenticated and delivered.
To the extent any provision of this Note conflicts with the express provisions of the Indenture, the provisions of the Indenture
shall govern and be controlling. All terms used in this Note and the Subsidiary Guarantee set forth below and that are not defined
herein shall have the meanings assigned to those terms in the Indenture. The series of which this Note is a part also is designated
as the Company’s 5.375% Senior Notes due 2027 (herein called the “Notes”), initially in the principal amount
of $500,000,000. The Trustee initially shall act as Security Registrar, Transfer Agent and Paying Agent in connection with the
Notes.


 


SECTION 2. No Sinking Fund. This
Note is not subject to any sinking fund.


 


SECTION 3. Redemption and Repayment.
(a) The Company may, at its option, and subject to the terms and conditions of Article 3 of the Base Indenture and Section 2.6
of the First Supplemental Indenture, redeem this Note, in whole at any time or in part from time to time (x) prior to the
Par Call Date at a redemption price equal to the greater of  (i) 100% of the aggregate principal amount of the Notes to
be redeemed and (ii) the sum of the present values of the Remaining Scheduled Payments, plus, in each case, accrued and unpaid
interest thereon to, but excluding, the redemption date, subject to the rights of holders of such Notes to be redeemed on the relevant
record date to receive interest due on an interest payment date that is on or prior to such redemption date or (y) on or after
the Par Call Date at a redemption price equal to 100% of the aggregate principal amount of such Notes to redeemed, plus accrued
and unpaid interest thereon to, but not including, the redemption date. Notwithstanding the foregoing, installments of interest
on this Note that are due and payable on Interest Payment Dates falling on or prior to a redemption date shall be payable on the
Interest Payment Date to the holders of this Note as of the close of business on the relevant record date according to this Note
and the Indenture. In determining the present values of the Remaining Scheduled Payments, the Company will discount such payments
to the redemption date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) using a discount rate
equal to the Treasury Rate plus 50 basis points.


 


(b) Notice of any redemption shall be given
at least 30 days but not more than 60 days before the redemption date to each holder of the Notes to be redeemed. Unless the Company
defaults in payment of the redemption price, on and after the redemption date, interest shall cease


 




     


     


    

 


to accrue on the Notes or portions thereof
called for redemption. If less than all of the Notes are to be redeemed, the Notes shall be selected by the Trustee on a pro
rata basis to the extent practicable in accordance with its customary procedures or applicable procedures of the Depository.


 


(c) Prior to publishing any notice of redemption
in connection with a redemption pursuant to Section 3(a) hereof, the Company will deliver to the Trustee an Officer’s Certificate
signed by the Chief Financial Officer or a Senior Vice President of the Company stating that the Company is entitled to redeem
the Notes and that the conditions precedent to redemption have occurred.


  


For purposes of the above:


 


“Comparable Treasury Issue”
means the United States Treasury security selected by an Independent Investment Banker as having an actual or interpolated maturity
comparable to the remaining term of the Notes to be redeemed that would be utilized, at the time of selection and in accordance
with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the remaining term
of such Notes (assuming for this purpose that the Notes mature on the Par Call Date).


 


“Comparable Treasury Price”
means, with respect to any redemption date, (1) the arithmetic average of the applicable Reference Treasury Dealer Quotations for
such redemption date after excluding the highest and lowest Reference Treasury Dealer Quotations, (2) if the Company obtains fewer
than four applicable Reference Treasury Dealer Quotations, the arithmetic average of all applicable Reference Treasury Dealer Quotations
for such redemption date or (3) if only one Reference Treasury Dealer Quotation is received, such quotation.


 


“Independent Investment Banker”
means one of the Reference Treasury Dealers, or their respective successors, as may be appointed from time to time by the Company;
provided, however, that if the foregoing ceases to be a primary U.S. Government securities dealer in the United States
(a “primary treasury dealer”), the Company will substitute another primary treasury dealer.


 


“Reference Treasury Dealers”
means Barclays Capital Inc., Citigroup Global Markets Inc., Credit Suisse Securities (USA) LLC, J.P. Morgan Securities LLC, TD
Securities (USA) LLC, and each of their respective successors and any other primary treasury dealers selected by the Company.


 


“Reference Treasury Dealer Quotations”
means, with respect to each Reference Treasury Dealer and any redemption date, the arithmetic average, as determined by the Company,
of the bid and asked prices for the applicable Comparable Treasury Issue (expressed in each case as a percentage of its principal
amount) quoted in writing to the Company by such Reference Treasury Dealer as of 3:30 p.m., New York City time, on the third business
day preceding such redemption date.


 


“Remaining Scheduled Payments”
means, with respect to any Note to be redeemed, the remaining scheduled payments of the principal thereof and interest thereon
that would be due


 




     


     


    

 


after the related redemption date but for such redemption, assuming
for this purpose that the Notes mature on the Par Call Date; provided, however, that, if such redemption date is
not an interest payment date with respect to such Note, the amount of the next scheduled interest payment thereon will be reduced
by the amount of interest accrued thereon to such redemption date.


 


“Treasury Rate” means,
with respect to any redemption date, the rate per annum equal to the semi-annual equivalent yield to maturity (computed as of the
third business day immediately preceding that redemption date or in the case of a discharge, prior to the deposit date) of the
applicable Comparable Treasury Issue. In determining this rate, the Company will assume a price for the applicable Comparable Treasury
Issue (expressed as a percentage of its principal amount) equal to the applicable Comparable Treasury Price for such redemption
date.


 


(d) Upon the occurrence of a Change in
Control Repurchase Event, Section 2.7 of the First Supplemental Indenture shall apply to the extent applicable.


 


(e) Any notice of redemption may be
given prior to the completion of any event or transaction related to such redemption, including any offering or other corporate
transaction, and any such redemption or notice may be subject to one or more conditions precedent, including the completion of
the related offering or corporate transaction. In addition, if such redemption or notice is subject to satisfaction of one or
more conditions precedent, such notice will state that the redemption date may be delayed until such time as any or all of such
conditions have been satisfied, or such redemption may not occur and such notice may be rescinded in the event that any or all
such conditions have not been satisfied by the redemption date, or by the redemption date so delayed.


 


SECTION 4. Defeasance. The provisions
of Article 8 of the First Supplemental Indenture and Article 14 of the Indenture apply to this Note.


 


SECTION 5. Events of Default. If
an Event of Default (as defined in the First Supplemental Indenture) shall occur with respect to this Note, the principal of all
the Notes may be declared due and payable, or may become automatically due and payable without any action by the holder of this
Note or the Trustee, in each case in the manner and with the effect provided in the Indenture.


 


SECTION 6. Modifications and Waivers.
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 this Note under the Indenture at any time by the Company with the consent
of the holders of not less than a majority of the aggregate principal amount of the Notes then Outstanding and affected by such
amendment and modification. The Indenture also contains provisions permitting the holders of a majority in aggregate principal
amount of the Notes then outstanding on behalf of the holders of all such Notes, 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 Note shall be conclusive and binding upon such holder and upon all future holders of this Note and of any Note
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 Note.


 


No recourse shall be had for the payment
of the principal of or the interest on this Note, or for any claim based hereon, or otherwise in respect hereof, or based on or
in respect of the Indenture or any indenture supplemental thereto, against any incorporator, stockholder, officer, or director,
as such, past, present, or future, of the Company or any predecessor or successor corporation, whether by virtue of any constitution,
statute, or rule of law, or by the enforcement of any assessment or penalty or otherwise, all such liability being, by the acceptance
hereof and as part of the consideration for issue hereof, expressly waived and released.


 




     


     


    

 


SECTION 7. Obligations Unconditional.
No reference herein to the Indenture and no provision of this Note or of the Indenture shall alter or impair the obligation of
the Company, which is absolute and unconditional, to pay the principal of and interest on this Note at the times, place, and rate,
and in the coin or currency, herein prescribed.


 


SECTION 8. Authorized Denominations.
The Notes are issuable only as registered Notes without coupons in the minimum denominations of Two Thousand Dollars ($2,000) and
