1.                                      Interest.

Suzano Austria GmbH, a limited liability company incorporated under the laws of the Republic of Austria (such company, and its successors and assigns under the Indenture hereinafter referred to as the “Issuer”), promises to pay interest on the principal amount of this Security at the rate per annum shown above.

The Issuer will pay interest semi-annually on January 15 and July 15 of each year, commencing on January 15, 2020 to the Paying Agent, which shall in turn distribute the interest in accordance with the Indenture. The Securities shall bear interest at the rate per annum of 6.000% from July 15, 2019. Interest on the Securities shall be computed on the basis of a 360-day year of twelve 30-day months. The Issuer shall pay interest on overdue principal, and pay interest on overdue interest, at the lesser of (i) 2.0% per annum higher than the per annum rate set forth in this Security and (ii) the maximum rate permitted by applicable law.

2.                                      Method of Payment.

The Issuer will pay interest on the Securities (except defaulted interest) to the Persons who are registered Holders at the close of business on January 13 or July 13 next preceding the interest payment date even if Securities are canceled after the record date and on or before the interest payment date. Holders must surrender Securities to a Paying Agent to collect principal payments. The Issuer will pay principal, premium, interest and Additional Amounts, if any, in money of the United States that at the time of payment is legal tender for payment of public and private debts. Payments in respect of the Securities represented by a Global Security (including principal, premium, interest and Additional Amounts, if any) will be made by wire transfer of immediately available funds to the accounts specified by DTC. The Issuer will make all payments in respect of a certificated Security (including principal, premium, interest and Additional Amounts, if any) at the office or agency of the Paying Agent or the Trustee, unless the Issuer elects to make such payments by mailing a check to the registered address of, or by wire transfer to, each Holder thereof; provided, however, that payments on a certificated Security will be made by wire transfer to a U.S. dollar account maintained by the payee with a bank in the United States for Holders of more than U.S.$10,000,000 of Securities, if such Holder elects payment by wire transfer by giving written notice to the Trustee or the applicable Paying Agent to such effect designating such account no later than 30 days immediately preceding the relevant due date for payment (or such other date as the Trustee may accept in its discretion).

The final payment on any Security in definitive, fully registered form shall be made only upon presentation and surrender of such Security at the office of the Paying Agent on the payment date.

If a payment date is a Legal Holiday, payment shall be made on the next succeeding day that is not a Legal Holiday, and no interest shall accrue for the intervening period. If a regular record date is a Legal Holiday, the record date shall not be affected.

The terms of the Securities include those stated in the Indenture. Terms defined in the Indenture and not defined herein have the meanings ascribed thereto in the Indenture. The Securities are subject to all such terms, and Securityholders are referred to the Indenture.

The Securities are general obligations of the Issuer. The Issuer shall be entitled to issue Additional Securities pursuant to Section 2.12 of the Indenture. The Initial Securities issued on the Issue Date, any Additional Securities and Securities issued in exchange therefor will be treated as a single class for all purposes under the Indenture. The Indenture contains covenants that limit the ability of the Company and its Subsidiaries to engage in transactions with Affiliates; create liens on assets; transfer or sell assets; guarantee indebtedness; consolidate, merge or transfer all or substantially all of its assets and the assets of its subsidiaries; and engage in sale/leaseback transactions. These covenants are subject to important exceptions and qualifications.

To the extent of any conflict between the terms of the Securities and the Indenture, the applicable terms of the Indenture shall govern.

5.                                      Optional Redemption.

(a)                                 Optional Redemption with a Make-Whole Premium. Prior to October 15, 2028, the Issuer may redeem the Securities, in whole at any time, or in part from time to time, at a redemption price equal to the greater of (1) 100.0% of the principal amount thereof, and (2) 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) as if the Securities were redeemed on 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) at the Treasury Rate plus 50 basis points, plus in each case any accrued and unpaid interest and Additional Amounts, if any, on such Securities to the Redemption Date, as calculated by the Independent Investment Banker; provided that Securities in an aggregate principal amount equal to at least U.S.$150 million remain outstanding immediately after the occurrence of any partial redemption of Securities. At any time on or after the Par Call Date, the Issuer will have the right to redeem the Securities, in whole or in part and from time to time, 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.

Exh-1-12

For purposes of the above:

“Par Call Date” means the date falling six months prior to the Maturity Date of the Securities.

“Treasury Rate” means, with respect to any Redemption Date, the rate per annum equal to the semi-annual equivalent yield to maturity or interpolated maturity (on a day count basis) of the Comparable Treasury Issue, 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.

“Comparable Treasury Issue” means the United States Treasury security or securities selected by an Independent Investment Banker as having an actual or interpolated maturity 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 a comparable maturity to the Par Call Date.

“Independent Investment Banker” means one of the Reference Treasury Dealers appointed by the Issuer.

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

“Reference Treasury Dealers” means BNP Paribas Securities Corp., ▇.▇. ▇▇▇▇▇▇ Securities LLC, ▇▇▇▇▇▇▇ Lynch, Pierce, ▇▇▇▇▇▇ & ▇▇▇▇▇ Incorporated and Mizuho Securities USA LLC or their respective Affiliates which are primary United States government securities dealers and not less than two other leading primary United States government securities dealers in New York City reasonably designated by the Issuer; provided that if any of the foregoing cease to be a primary United States government securities dealer in New York City (a “Primary Treasury Dealer”), the Issuer will substitute therefor another Primary Treasury Dealer.

“Reference Treasury Dealer Quotation” means, with respect to each Reference Treasury Dealer and any Redemption Date, the average, as determined by the Independent Investment Banker, of the bid and asked price for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the Independent Investment Banker by such Reference Treasury Dealer at 3:30 pm New York time on the third Business Day preceding such Redemption Date.

(b)                                 Redemption for Taxation Reasons. If as a result of any change in or amendment to the laws or treaties (or any rules or regulations thereunder) of any Relevant 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 of the Securities or on or, with respect to a successor, after the date a successor assumes the obligations under the Securities, the Issuer or the Company or the successor have or will become obligated to pay Additional Amounts as described under Section 4.13 of the Indenture in excess of the Additional Amounts that the Issuer or the Company would be obligated to pay if payments were subject to

Exh-1-13

withholding or deduction at a rate of 15.0% (or at a rate of 25.0% in case the holder of the Securities 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 20.0%, 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”), the Issuer may, at its option, redeem all, but not less than all, of the Securities, at a redemption price equal to 100.0% 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 30 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 Issuer would, but for such redemption, be obligated to pay the Additional Amounts above the Minimum Withholding Level, were a payment then due. The Issuer shall not have the right to so redeem the Securities 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 Issuer shall not have the right to so redeem the Securities 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 Issuer’s, the Company’s or any successor’s jurisdiction of incorporation or organization or location of its principal executive or registered office.

In the event that the Issuer elects to so redeem the Securities, it shall deliver to the Trustee: (i) a certificate, signed in the name of the Issuer by two of its directors or by its attorney-in-fact in accordance with its articles of association, stating that the Issuer is entitled to redeem the Securities pursuant to their terms and setting forth a statement of facts showing that the condition or conditions precedent to the right of the Issuer 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.

6.                                      Redemption Procedures.

The Issuer shall give or cause the Trustee to give notice of redemption, in the manner provided for in Section 11.01 of the Indenture, not less than 30 nor more than 60 days prior to a date for redemption of Securities by first-class mail, postage prepaid, to each Securityholder at its registered address or otherwise in accordance with the procedures of DTC. If the Issuer itself gives the notice, it shall also deliver a copy at the same time to the Trustee.

If the Issuer elects to have the Trustee give notice of redemption the Issuer shall deliver to the Trustee, at least 45 days prior to the Redemption Date (unless the Trustee is satisfied with a shorter period), an Officer’s Certificate requesting that the Trustee select the Securities to be redeemed and/or give notice of redemption and setting forth the information required by Section 3.02(c) of the Indenture. If the Issuer elects to have the Trustee give notice of redemption, the Trustee shall give the notice in the name of the Issuer and at the Issuer’s expense. Securities will be selected for partial redemptions in accordance with DTC procedures.

Exh-1-14

If the Issuer, or the Trustee on behalf of the Issuer, gives notice of redemption in accordance with Article III of the Indenture, the Securities shall, on the Redemption Date, become due and payable at the redemption price specified in the notice (together with accrued interest, if any, to, but excluding, the Redemption Date), and from and after the Redemption Date (unless the Issuer shall default in the payment of the redemption price and accrued interest) the Securities shall cease to bear interest. Upon surrender of the Securities for redemption in accordance with the notice, the Issuer shall pay the Securities at the redemption price, together with accrued interest, if any, to, but excluding, the Redemption Date. If the Issuer shall fail to pay any Security called for redemption upon its surrender for redemption, the principal shall, until paid, bear interest from the Redemption Date at the rate borne by the Securities.

7.                                      Put Provisions.

Upon a Change of Control that results in a Rating Decline, any Holder will have the right to cause the Issuer and the Company to repurchase all or any part (equal to U.S.$200,000 and integral multiples of U.S.$1,000 in excess thereof) of the Securities of such Holder at a repurchase price equal to 101.0% of the aggregate principal amount of the Securities to be repurchased plus accrued and unpaid interest and Additional Amounts, if any, to the date of repurchase, as provided in, and subject to the terms of, the Indenture.

The Securities shall be issued in registered form in denominations of U.S.$200,000 and integral multiples of U.S.$1,000 in excess thereof and shall be issued as one or more Global Securities. A Holder may transfer or exchange Securities in accordance with the Indenture. The Securities may be transferred, combined or divided without payment of any charge other than taxes or other governmental charges. The Registrar may require a Holder, among other things, to furnish appropriate endorsements or transfer documents and to pay any taxes and fees required by law or permitted by the Indenture. The Registrar need not register the transfer of or exchange any Securities selected for redemption or any Securities for a period of 15 days before a selection of Securities to be redeemed or 15 days before an Interest Payment Date.

11.                               Persons Deemed Owners.

The registered Holder of this Security may be treated as the owner of it for all purposes. Payment shall be made to the person in whose name a Security is registered at the close of business on the applicable record date.

13.                               Discharge; Defeasance.

Subject to certain conditions set forth in Article VIII of the Indenture, the Issuer shall be entitled to terminate some or all of its obligations under the Securities and the Indenture if the Issuer deposits with the Trustee cash or U.S. Government Obligations for the payment of principal and interest on the Securities upon redemption or maturity, as the case may be.

Under the Indenture, Events of Default include (a) default for 30 days in payment of any interest or related Additional Amounts, if any, on the Securities; (b) default in payment of principal of or any related Additional Amounts, if any, or premium, if any, on the Securities, when the same becomes due and payable at maturity, upon acceleration or redemption, or otherwise; (c) failure by the Company to comply with Section 5.01; (d) failure by the Issuer or the Company, as the case may be, to comply with other agreements in the Indenture and such non-compliance continues for a period of 60 consecutive days after written notice is given to Issuer and/or the Company by the Trustee or to the Issuer, the Company and the Trustee by the Holders of at least 25.0% in aggregate principal amount of the Securities; (e) certain accelerations of other Debt of the Company; (f) certain events of bankruptcy or insolvency with respect to the Issuer, the Company or any Subsidiary; (g) the Company Guarantee shall fail to be in full force and effect or is declared null and void; and (h)

If an Event of Default occurs and is continuing, the Trustee or the Holders of at least 25.0% in principal amount of the Securities, by written notice to the Issuer and the Company (and to the Trustee if notice is given by the Holders), may declare all the Securities to be due and payable immediately. Certain events of bankruptcy or insolvency are Events of Default which will result in the Securities being due and payable immediately upon the occurrence of such Events of Default.

Securityholders may not enforce the Indenture or the Securities except as provided in the Indenture. The Trustee may refuse to enforce the Indenture or the Securities unless it receives indemnity or security reasonably satisfactory to it. Subject to certain limitations, Holders of a majority in principal amount of the Securities may direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Securityholders notice of any continuing Default (except a Default in payment of principal or interest) if it determines that withholding notice is in the interest of the Holders.

16.                               Trustee Dealings with the Issuer and the Company.

Subject to certain limitations imposed by the TIA, the Trustee under the Indenture, in its individual or any other capacity, may become the owner or pledgee of Securities and may otherwise deal with and collect obligations owed to it by the Issuer, the Company or their Affiliates and may otherwise deal with the Issuer, the Company or their Affiliates with the same rights it would have if it were not Trustee.

17.                               No Recourse Against Others.

No past, present or future director, officer, employee, partner, incorporator, quotaholder, member or shareholder, as such, of the Issuer, the Company or any Subsidiary of the Company, shall have any liability for any obligations of the Issuer, the Company or any Subsidiary of the Company under the Securities, the Indenture or the Company Guarantee or for any claim based on, in respect of or by reason of such obligations or their creation. By accepting a Security, each Securityholder waives and releases all such liability. The waiver and release are part of the consideration for the issue of the Securities.

18.                               Authentication.

This Security shall not be valid until an authorized signatory of the Trustee (or an authenticating agent) manually signs the certificate of authentication on the other side of this Security.

19.                               Abbreviations.

Customary abbreviations may be used in the name of a Securityholder or an assignee, such as TEN COM (=tenants in common), TEN ENT (=tenants by the entireties), JT TEN (=joint tenants with rights of survivorship and not as tenants in common), CUST (=custodian) and U/G/M/A (=Uniform Gift to Minors Act).

20.                               CUSIP Numbers and ISINs.

Pursuant to a recommendation promulgated by the Committee on Uniform Security Identification Procedures, the Issuer has caused CUSIP numbers or ISINs to be printed on the Securities and has directed the Trustee to use CUSIP numbers or ISINs in notices of redemption as a convenience to Securityholders. No representation is made as to the accuracy of such numbers either as printed on the Securities or as contained in any notice of redemption, and reliance may be placed only on the other identification numbers placed thereon.

21.                               Governing Law; Consent to Jurisdiction and Service of Process.

THIS SECURITY SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK BUT WITHOUT GIVING EFFECT TO APPLICABLE PRINCIPLES OF CONFLICTS OF LAW TO THE EXTENT THAT THE APPLICATION OF THE LAWS OF ANOTHER JURISDICTION WOULD BE REQUIRED THEREBY.

Each of the Issuer and the Company has consented to the jurisdiction of the courts of the State of New York and the United States courts located in the Borough of Manhattan, New York City, New York with respect to any action that may be brought in connection with the Indenture or the Securities and has validly and effectively appointed Corporation Service Company as agent for service of process.
