WHEREAS, the Issuer, the Guarantor and the Trustee intend the Reopening Notes to be consolidated, form a single series and be fully
fungible with the Company’s outstanding 5.375% Global Notes due 2021 originally issued on January 27, 2011 under the Original Indenture as supplemented by the Sixth Supplemental Indenture dated as of January 27, 2011, by and among the
Issuer, the Guarantor and the Trustee, in the aggregate principal amount of $2,500,000,000 (the “Original Notes” and, together with the Reopening Notes, the “2021 Notes”); 

WHEREAS, the Guarantor is willing to enter into this Amended and Restated Guaranty in order to provide the holders of the 2021 Notes (the
“Noteholders”) with an irrevocable and unconditional guaranty that, if the Issuer shall fail to make any required payments of principal, interest or other amounts due in respect of the 2021 Notes and the Indenture, the Guarantor
will pay any such amounts whether at stated maturity, or earlier or later by acceleration or otherwise; 
 WHEREAS, the
Guarantor agrees that it will derive substantial direct and indirect benefits from the issuance of the 2021 Notes by the Issuer; 
 WHEREAS, it is a condition precedent to the issuance of the 2021 Notes that the Guarantor shall have executed this Amended and Restated Guaranty.

(iii) any provision of applicable Law or regulation purporting to prohibit the payment by the Guarantor of any amount
payable by it under this Amended and Restated Guaranty; 
 (iv) any change in the time, manner or place of
payment of, or in any other term of, all or any of the Guaranteed Obligations or any other obligations of any other person or entity under or in respect of the Transaction Documents, or any other amendment or waiver of or any consent to departure
from any Transaction Document, including, without limitation, any increase in the obligations of the Issuer under the Indenture and the 2021 Notes as a result of further issuances, any rescheduling of the Issuer’s obligations under the 2021
Notes of the Indenture or otherwise; 
 (v) any taking, release or amendment or waiver of, or consent to
departure from, any other guaranty or agreement similar in function to this Amended and Restated Guaranty, for all or any of the obligations of the Issuer under the Indenture or the 2021 Notes; 

(vi) any manner of sale or other disposition of any assets of any Noteholder; 

(vii) any change, restructuring or termination of the corporate structure or existence of the Issuer or the Guarantor or
any Subsidiary thereof or any change in the name, purposes, business, capital stock (including ownership thereof) or constitutive documents of the Issuer or the Guarantor; 

(viii) any failure of the Trustee to disclose to the Guarantor any information relating to the business, condition
(financial or otherwise), operations, performance, properties or prospects of the Issuer or any of its Subsidiaries (the Guarantor hereby waiving any duty on the part of the Trustee or any Noteholders to disclose such information); 

  
 7 

 (ix) the failure of any other person or entity to execute or deliver any
other guaranty or agreement or the release or reduction of liability of any other guarantor or surety with respect to the Indenture; 
 (x) any other circumstance (including, without limitation, any statute of limitations) or any existence of or reliance on any representation by the Trustee or any Noteholder that might otherwise
constitute a defense available to, or a discharge of, the Issuer or the Guarantor or any other party; or 
 (xi)
any claim of set-off or other right which the Guarantor may have at any time against the Issuer or the Trustee, whether in connection with this transaction or with any unrelated transaction. 

(b) This Amended and Restated Guaranty shall continue to be effective or be reinstated, as the case may be, if at any time any payment of
any of the Guaranteed Obligations is rescinded or must otherwise be returned by any Noteholder or any other person or entity upon the insolvency, bankruptcy or reorganization of the Issuer or the Guarantor or otherwise, all as though such payment
had not been made. 
 SECTION 4. Independent Obligation. The obligations of the Guarantor hereunder are independent of
the Issuer’s obligations under the 2021 Notes and the Indenture. The Trustee, on behalf of the Noteholders, may neglect or forbear to enforce payment under the Indenture and the 2021 Notes, without in any way affecting or impairing the
liability of the Guarantor hereunder. The Trustee shall not be obligated to exhaust recourse or remedies against the Issuer to recover payments required to be made under the Indenture nor take any other action against the Issuer before being
entitled to payment from the Guarantor of all amounts contemplated in Section 2 hereof owed hereunder or proceed against or have resort to any balance of any deposit account or credit on the books of the Trustee in favor of the Issuer or in
favor of the Guarantor. Without limiting the generality of the foregoing, the Trustee shall have the right to bring a suit directly against the Guarantor, either prior or subsequent to or concurrently with any lawsuit against, or without bringing
suit against, the Issuer. 
 SECTION 5. Waivers and Acknowledgments. (a) The Guarantor hereby unconditionally and
irrevocably waives promptness, diligence, notice of acceptance, presentment, demand for performance, notice of nonperformance, default, acceleration, protest or dishonor and any other notice with respect to any of the Guaranteed Obligations and this
Amended and Restated Guaranty and any requirement that the Trustee, on behalf of the Noteholders, protect, secure, perfect or insure any Lien or any property subject thereto or exhaust any right or take any action against the Issuer or any other
Person. 
 (b) The Guarantor hereby unconditionally and irrevocably waives any right to revoke this Amended and Restated
Guaranty and acknowledges that this Amended and Restated Guaranty is continuing in nature and applies to the Guaranteed Obligations, whether the same are existing now or in the future. 

  
 8 

 (c) The Guarantor hereby unconditionally and irrevocably waives (i) any defense arising
by reason of any claim or defense based upon an election of remedies by any Noteholder or the Trustee on behalf of the Noteholders that in any manner impairs, reduces, releases or otherwise adversely affects the subrogation, reimbursement,
exoneration, contribution or indemnification rights of the Guarantor or other rights of the Guarantor to proceed against the Issuer or any other person or entity and (ii) any defense based on any right of set-off or counterclaim against or in
respect of the Guaranteed Obligations of the Guarantor hereunder. 
 (d) The Guarantor hereby unconditionally and irrevocably
waives any duty on the part of the Trustee or any Noteholder to disclose to the Guarantor any matter, fact or thing relating to the business, condition (financial or otherwise), operations, performance, properties or prospects of the Issuer now or
hereafter known by the Trustee or any Noteholder, as applicable. 
 (e) The Guarantor acknowledges that it will receive
substantial direct and indirect benefits from the financing arrangements contemplated by the Transaction Documents and that the waivers set forth in this Section 5 are knowingly made in contemplation of such benefits. 

(f) The recitals contained in this Amended and Restated Guaranty shall be taken as the statements of the Issuer and the Guarantor, as
applicable, and the Trustee assumes no responsibility for the correctness of the same. The Trustee makes no representation as to the validity or sufficiency of this Amended and Restated Guaranty, of any offering materials, the Indenture or of the
2021 Notes. 
 (g) The Guarantor unconditionally and irrevocably waives, to the fullest extent permitted under Brazilian law,
any benefit it may be entitled to under Articles 827, 834, 835, 838 and 839 of the Brazilian Civil Code, and under Article 595, caput, of the Brazilian Civil Procedure Code. 

  
 9 

 SECTION 6. Claims Against the Issuer. The Guarantor hereby unconditionally and
irrevocably agrees not to exercise any rights that it may now have or hereafter acquire against the Issuer or any other guarantor that arise from the existence, payment, performance or enforcement of the Guarantor’s obligations under or in
respect of this Amended and Restated Guaranty or any other Transaction Document, including, without limitation, any right of subrogation, reimbursement, exoneration, contribution or indemnification, or to participate in any claim or remedy of the
Trustee, on behalf of the Noteholders, against the Issuer or any other person, whether or not such claim, remedy or right arises in equity or under contract, statute or common law, including, without limitation, the right to take or receive from the
Issuer or any other person, directly or indirectly, in cash or other property or by set-off or in any other manner, payment or security on account of such claim, remedy or right, unless and until all of the Guaranteed Obligations and all other
amounts payable under this Amended and Restated Guaranty shall have been paid in full in cash. If any amount shall be paid to the Guarantor in violation of the immediately preceding sentence at any time prior to the later of (a) the payment in
full in cash of the Guaranteed Obligations and all other amounts payable under this Amended and Restated Guaranty and (b) the date on which all of the obligations of the Issuer under the Indenture and the 2021 Notes have been discharged in full
(the later of such dates being the “Termination Date”), such amount shall be paid over to and received and held by the Trustee in trust for the benefit of the Noteholders, shall be segregated from other property and funds of the
Guarantor and shall forthwith be paid or delivered to the Trustee in the same form as so received (with any necessary endorsement or assignment) to be credited and applied to the Guaranteed Obligations and all other amounts payable under this
Amended and Restated Guaranty, whether matured or unmatured, in accordance with the terms of the Indenture. If (i) the Guarantor shall make payment to any Noteholder or the Trustee, on behalf of the Noteholders, of all or any part of the
Guaranteed Obligations, (ii) all of the Guaranteed Obligations and all other amounts payable under this Amended and Restated Guaranty shall have been paid in full in cash and (iii) the Termination Date shall have occurred, then the
Trustee, on behalf of the Noteholders, will, at the Guarantor’s written request and expense, execute and deliver to the Guarantor appropriate documents, without recourse and without representation or warranty, necessary to evidence the transfer
by subrogation to the Guarantor of an interest in the Guaranteed Obligations resulting from such payment made by the Guarantor pursuant to this Amended and Restated Guaranty. 
 SECTION 7. Covenants. For so long as the 2021 Notes remain outstanding or any amount remains unpaid on the 2021 Notes and the Indenture, the Guarantor will, and will cause each of its Subsidiaries,
as applicable, to comply with the terms and covenants set forth below (except as otherwise provided in a duly authorized amendment to this Amended and Restated Guaranty as provided herein): 

(a) Performance of Obligations. The Guarantor shall pay all amounts owed by it and comply with all its other obligations under the
terms of this Amended and Restated Guaranty and the Indenture in accordance with the terms thereof. 
 (b) Maintenance of
Corporate Existence. The Guarantor will (i) maintain in effect its corporate existence and all registrations necessary therefor except as otherwise permitted by Section 7 (f) and (ii) take all actions to maintain all rights,
privileges, titles to property, franchises, concessions and the like necessary or desirable in the normal conduct of its 

  
 10 

 
business, activities or operations; provided, however, that this Section 7(b) shall not require the Guarantor to maintain any such right, privilege, title to property or franchise if
the failure to do so does not, and will not, have a Material Adverse Effect. 
 (c) Maintenance of Office or Agency. So
long as any of the 2021 Notes are outstanding, the Guarantor will maintain in the Borough of Manhattan, The City of New York, an office or agency where notices to and demands upon the Guarantor in respect of this Amended and Restated Guaranty may be
served, and the Guarantor will not change the designation of such office without prior written notice to the Trustee and designation of a replacement office in the same general location. 

(d) Ranking. The Guarantor will ensure at all times that its obligations under this Amended and Restated Guaranty will constitute
the general senior unsecured and unsubordinated obligations of the Guarantor and will rank pari passu, without any preferences among themselves, with all other present and future senior unsecured and unsubordinated obligations of the
Guarantor (other than obligations preferred by statute or by operation of law) that are not, by their terms, expressly subordinated in right of payment to the obligations of the Guarantor under this Amended and Restated Guaranty. 

(e) Notice of Defaults. The Guarantor will give written notice to the Trustee, as soon as is practicable and in any event within
ten calendar days after the Guarantor becomes aware, or should reasonably become aware, of the occurrence of any Default or Event of Default, accompanied by a certificate of an officer of the Guarantor setting forth the details thereof and stating
what action the Guarantor proposes to take with respect thereto. 
 (f) Limitation on Consolidation, Merger, Sale or
Conveyance. (i) The Guarantor will not, in one or a series of transactions, consolidate or amalgamate with or merge into any corporation or convey, lease or transfer substantially all of its properties, assets or revenues to any person or
entity (other than a direct or indirect Subsidiary of the Guarantor) or permit any person or entity (other than a direct or indirect Subsidiary of the Guarantor) to merge with or into it, unless: 

(A) either the Guarantor is the continuing entity or the person (the “Successor Company”) formed by such
consolidation or into which the Guarantor is merged or that acquired or leased such property or assets of the Guarantor will assume (jointly and severally with the Guarantor unless the Guarantor shall have ceased to exist as a result of such merger,
consolidation or amalgamation), by an amendment to this Amended and Restated Guaranty (the form and substance of which shall be previously approved by the Trustee), all of the Guarantor’s obligations under this Amended and Restated Guaranty;

 (B) the Successor Company (jointly and severally with the Guarantor unless the Guarantor shall have ceased to
exist as part of such merger, consolidation or amalgamation) agrees to indemnify each Noteholder against any tax, assessment or governmental charge thereafter imposed on such Noteholder solely as a consequence of such consolidation, merger,
conveyance, transfer or lease with respect to the payment of principal of, or interest on, the 2021 Notes pursuant to this Amended and Restated Guaranty; 

  
 11 

 (C) immediately after giving effect to such transaction, no Event of
Default, and no Default has occurred and is continuing; and 
 (D) the Guarantor has delivered to the Trustee an
Officer’s Certificate and an Opinion of Counsel, each stating that such merger consolidation, sale, transfer or other conveyance or disposition and the amendment to this Amended and Restated Guaranty comply with the terms of this Amended and
Restated Guaranty and that all conditions precedent provided for herein and relating to such transaction have been complied with. 
 (ii) Notwithstanding anything to the contrary in the foregoing, so long as no Default or Event of Default shall have occurred and be continuing at the time of such proposed transaction or would result
therefrom and the Guarantor has delivered written notice of any such transaction to the Trustee (which notice shall contain a description of such merger, consolidation or conveyance): 

(A) the Guarantor may merge, amalgamate or consolidate with or into, or convey, transfer, lease or otherwise dispose of
all or substantially all of its properties, assets or revenues to a direct or indirect Subsidiary of the Guarantor in cases when the Guarantor is the surviving entity in such transaction and such transaction would not have a Material Adverse Effect
on the Guarantor and its Subsidiaries taken as a whole, it being understood that if the Guarantor is not the surviving entity, the Guarantor shall be required to comply with the requirements set forth in the previous paragraph; or 

(B) any direct or indirect Subsidiary of the Guarantor may merge or consolidate with or into, or convey, transfer, lease
or otherwise dispose of assets to, any person (other than the Guarantor or any of its Subsidiaries or Affiliates) in cases when such transaction would not have a Material Adverse Effect on the Guarantor and its Subsidiaries taken as a whole; or

 (C) any direct or indirect Subsidiary of the Guarantor may merge or consolidate with or into, or convey,
transfer, lease or otherwise dispose of assets to, any direct or indirect Subsidiary of the Guarantor; or 
 (D)
any direct or indirect Subsidiary of the Guarantor may liquidate or dissolve if the Guarantor determines in good faith that such liquidation or dissolution is in the best interests of the Guarantor, and would not result in a Material Adverse Effect
on the Guarantor and its Subsidiaries taken as a whole and if such liquidation or dissolution is part of a corporate reorganization of the Guarantor. 
 (g) Negative Pledge. So long as any 2021 Note remains outstanding, the Guarantor will not create or permit any Lien, other than a Permitted Lien, on any of the Guarantor’s assets to secure
(i) any of the Guarantor’s Indebtedness or (ii) the Indebtedness of any other person, unless the Guarantor contemporaneously creates or permits such Lien to secure equally and ratably the Guarantor’s obligations under this
Amended and Restated Guaranty or the Guarantor provides such other security for the 2021 Notes as is duly approved by the Trustee, at the direction of the Noteholders, in accordance with the Indenture. In addition, the Guarantor will not allow any
of the Guarantor’s Material Subsidiaries to create or permit any Lien, other 

  
 12 

 
than a Permitted Lien, on any of the Guarantor’s assets to secure (i) any of the Guarantor’s Indebtedness, (ii) any of the Indebtedness of the Guarantor’s Material
Subsidiaries or (iii) the Indebtedness of any other person, unless it contemporaneously creates or permits the Lien to secure equally and ratably the Guarantor’s obligations under this Amended and Restated Guaranty or the Guarantor or such
Material Subsidiary provides such other security for the 2021 Notes as is duly approved by the Trustee, at the direction of the Noteholders, in accordance with the Indenture. 
 (h) Provision of Financial Statements and Reports. (i) The Guarantor will provide to the Trustee, in English or accompanied by a certified English translation thereof, (A) within 90
calendar days after the end of each fiscal quarter (other than the fourth quarter), its unaudited and consolidated balance sheet and statement of income calculated in accordance with Reporting GAAP, (B) within 120 calendar days after the end of
each fiscal year, its audited and consolidated balance sheet and statement of income calculated in accordance with Reporting GAAP and (C) such other financial data as the Trustee may reasonably request. 

(ii) The Guarantor will provide, together with each of the financial statements delivered pursuant to Sections 7(h)(i)(A) and (B), an
Officer’s Certificate stating that a review of the activities of the Guarantor and the Issuer has been made during the period covered by such financial statements with a view to determining whether the Guarantor and the Issuer have kept,
observed, performed and fulfilled their covenants and agreements under this Amended and Restated Guaranty and that no Default or Event of Default has occurred during such period or, if one or more have actually occurred, specifying all such events
and what actions have been taken and will be taken with respect to such Default or Event of Default. 
 (iii) The
Guarantor shall, whether or not it is required to file reports with the SEC, file with the SEC and deliver to the Trustee (for redelivery to all Noteholders) all reports and other information as it would be required to file with the SEC under the
Exchange Act if it were subject to those regulations; provided, however, that if the SEC does not permit the filing described in the first sentence of this Section 7(h)(iii), the Guarantor will provide annual and interim reports and
other information to the Trustee within the same time periods that would be applicable if the Guarantor were required and permitted to file these reports with the SEC. 

(iv) Upon written request of any Holder or The Depository Trust Company (DTC), the reports and other information provided
for in this paragraph (h) shall be delivered to DTC representing the Noteholders, at 55 Water Street, 25th Floor, New York, NY, 10041, Attention: Proxy Department, or such other address as DTC may provide to the Trustee in writing. 

(v) Delivery of the above reports to the Trustee is for informational purposes only and the Trustee’s receipt of such
reports shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including the Guarantor’s compliance with any of its covenants in the Indenture (as to which the Trustee
is entitled to rely exclusively on an Officer’s Certificate). 

  
 13 

 SECTION 8. Amendments, Etc. No amendment or waiver of any provision of this Amended
and Restated Guaranty and no consent to any departure by the Guarantor therefrom shall in any event be effective unless the same shall be in writing and signed by the Trustee and the Guarantor, and then such waiver or consent shall be effective only
in the specific instance and for the specific purpose for which given. For the avoidance of doubt, Article IX of the Indenture shall apply to an amendment to this Amended and Restated Guaranty to determine whether the consent of Holders is required
for an amendment and if so, the required percentage of Holders of the 2021 Notes required to approve the amendment. 
 SECTION
9. Indemnity. The Guarantor agrees to fully indemnify the Trustee and any predecessor Trustee and their agents for, and to hold it harmless against, any and all loss, liability, damages, claims or expense arising out of or in connection with
the performance of its duties under this Amended and Restated Guaranty, including the costs and expenses of defending itself against any claim or liability in connection with the exercise or performance of any of its powers or duties hereunder
except to the extent that any such loss, liability or expense may be attributable to its negligence or bad faith. 
 SECTION 10.
Notices, Etc. (a) All notices and other communications provided for hereunder shall be in writing (including telegraphic or telecopy) and mailed, telecopied or delivered by hand, if to the Guarantor, addressed to it at Avenida

 (b) All payments made by the Guarantor to the Trustee hereunder shall be made to the Payment Account (as defined in the Indenture). 

  
 14 

 SECTION 11. Survival. Without prejudice to the survival of any of the other
agreements of the Guarantor under this Amended and Restated Guaranty or any of the other Transaction Documents, the agreements and obligations of the Guarantor contained in Section 2 (with respect to the payment of all other amounts owed under
the Indenture), Section 9 and Section 14 shall survive the payment in full of the Guaranteed Obligations and all of the other amounts payable under this Amended and Restated Guaranty, the termination of this Amended and Restated Guaranty
and/or the resignation or removal of the Trustee. 
 SECTION 12. No Waiver; Remedies. No failure on the part of the
Trustee to exercise, and no delay in exercising, any right hereunder shall operate as a waiver thereof; nor shall any single or partial exercise of any right hereunder preclude any other or further exercise thereof or the exercise of any other
right. The remedies herein provided are cumulative and not exclusive of any remedies provided by law. 
 SECTION 13.
Continuing Agreement; Assignment of Rights Under the Indenture and the 2021 Notes. This Amended and Restated Guaranty is a continuing guaranty and shall (a) remain in full force and effect until the later of (i) the repayment in
full by the Issuer of all amounts due and owing under the Indenture with respect to the 2021 Notes and (ii) the repayment in full of all Guaranteed Obligations and all other amounts payable under this Amended and Restated Guaranty, (b) be
binding upon the Guarantor, its successors and assigns and (c) inure to the benefit of and be enforceable by the Trustee, on behalf of Noteholders, and their successors, transferees and assigns. Without limiting the generality of clause
(c) of the immediately preceding sentence, any Noteholder may assign or otherwise transfer its rights and obligations under the Indenture (including, without limitation, the 2021 Notes held by it) to any other person or entity, and such other
person or entity shall thereupon become vested with all the benefits in respect thereof granted to such Noteholder herein or otherwise, in each case as and to the extent provided in the Indenture. The Guarantor shall not have the right to assign its
rights hereunder or any interest herein without the prior written consent of all of the Noteholders. 
 SECTION 14. Currency
Rate Indemnity. (a) The Guarantor shall (to the extent lawful) indemnify the Trustee and the Noteholders and keep them indemnified against: 
 (i) in the case of nonpayment by the Guarantor of any amount due to the Trustee, on behalf of the Noteholders, under this Amended and Restated Guaranty any loss or damage incurred by any of them arising
by reason of any variation between the rates of exchange used for the purposes of calculating the amount due under a judgment or order in respect thereof and those prevailing at the date of actual payment by the Guarantor; and 

(ii) any deficiency arising or resulting from any variation in rates of exchange between (a) the date as of which the
local currency equivalent of the amounts due or contingently due under this Amended and Restated Guaranty or in respect of the 2021 Notes is calculated for the purposes of any bankruptcy, insolvency or liquidation of the Guarantor, and (b) the
final date for ascertaining the amount of claims in such bankruptcy, insolvency or liquidation. The amount of such deficiency shall be deemed not to be increased or reduced by any variation in rates of exchange occurring between the said final date
and the date of any bankruptcy, insolvency or liquidation or any distribution of assets in connection therewith. 

  
 15 

 (b) The Guarantor agrees that, if a judgment or order given or made by any court for the
payment of any amount in respect of its obligations hereunder is expressed in a currency (the “Judgment Currency”) other than U.S. dollars (the “Denomination Currency”), it will indemnify the relevant Holder and the
Trustee against any deficiency arising or resulting from any variation in rates of exchange between the date at which the amount in the Denomination Currency is notionally converted into the amount in the Judgment Currency for the purposes of such
judgment or order and the date of actual payment thereof. 
 (c) The above indemnities shall constitute separate and independent
obligations of the Guarantor from its obligations hereunder, will give rise to separate and independent causes of action, will apply irrespective of any indulgence granted from time to time and will continue in full force and effect notwithstanding
any judgment or the filing of any proof or proofs in any bankruptcy, insolvency or liquidation of the Guarantor for a liquidated sum or sums in respect of amounts due under this Amended and Restated Guaranty, or under the Indenture or the 2021 Notes
or under any judgment or order. 
 SECTION 15. Governing Law; Jurisdiction; Waiver of Immunity, Etc. 

(a) This Amended and Restated Guaranty shall be governed by, and construed in accordance with, the laws of the State of New York.

 (b) The Guarantor hereby irrevocably and unconditionally submits, for itself and its property, to the nonexclusive
jurisdiction of any New York State court or federal court of the United States of sitting in New York City, and any appellate court from any thereof, in any action or proceeding arising out of or relating to this Amended and Restated Guaranty or any
of the other Transaction Documents to which it is or is to be a party, or for recognition or enforcement of any judgment, and the Guarantor hereby irrevocably and unconditionally agrees that all claims in respect of any such action or proceeding may
be heard and determined in any such New York State court or, to the extent permitted by law, in such federal court. The Guarantor agrees that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other
jurisdictions by suit on the judgment or in any other manner provided by law. Nothing in this Amended and Restated Guaranty or any other Transaction Document shall affect any right that any party may otherwise have to bring any action or proceeding
against the Issuer or the Guarantor, as the case may be, relating to this Amended and Restated Guaranty or any other Transaction Document in the courts of any jurisdiction. 
 (c) The Guarantor hereby irrevocably appoints and empowers the New York office of Petróleo Brasileiro S.A., located at 570 Lexington Avenue, 43rd Floor, New York, New York 10022 as its authorized
agent (the “Process Agent”) to accept and acknowledge for and on its behalf and on behalf of its property service of any and all legal process, summons, notices and documents which may be served in any such suit, action or
proceedings in any New York State court or United States federal court sitting in the State of New York in the Borough of Manhattan and any appellate court from any thereof, which service may be made on such designee, appointee and agent in
accordance with legal procedures prescribed for such courts. The 

  
 16 

 
Guarantor will take any and all action necessary to continue such designation in full force and effect and to advise the Trustee of any change of address of such Process Agent and; should such
Process Agent become unavailable for this purpose for any reason, the Guarantor will promptly and irrevocably designate a new Process Agent within New York, New York, which will agree to act as such, with the powers and for the purposes specified in
this subsection (c). The Guarantor irrevocably consents and agrees to the service of any and all legal process, summons, notices and documents out of any of the aforesaid courts in any such action, suit or proceeding by hand delivery, to it at its
address set forth in Section 10 or to any other address of which it shall have given notice pursuant to Section 10 or to its Process Agent. Service upon the Guarantor or the Process Agent as provided for herein will, to the fullest extent
permitted by law, constitute valid and effective personal service upon it and the failure of the Process Agent to give any notice of such service to the Guarantor shall not impair or affect in any way the validity of such service or any judgment
rendered in any action or proceeding based thereon. 
 (d) The Guarantor irrevocably and unconditionally waives, to the fullest
extent it may legally and effectively do so, any objection that it may now or hereafter have to the laying of venue of any suit, action or proceeding arising out of or relating to this Amended and Restated Guaranty or any of the other Transaction
Documents to which it is or is to be a party in any New York State or federal court. The Guarantor hereby irrevocably waives, to the fullest extent permitted by law, the defense of an inconvenient forum to the maintenance of such suit, action or
proceeding in any such court. 
 (e) THE GUARANTOR HEREBY IRREVOCABLY WAIVES ALL RIGHT TO TRIAL BY JURY IN ANY ACTION,
PROCEEDING OR COUNTERCLAIM (WHETHER BASED ON CONTRACT, TORT OR OTHERWISE) ARISING OUT OF OR RELATING TO THIS GUARANTY, ANY OF THE TRANSACTION DOCUMENTS, THE ADVANCES OR THE ACTIONS OF ANY NOTEHOLDER IN THE NEGOTIATION, ADMINISTRATION, PERFORMANCE OR
ENFORCEMENT THEREOF. 
 (f) This Amended and Restated Guaranty and any other documents delivered pursuant hereto, and any
actions taken hereunder, constitute commercial acts by the Guarantor. The Guarantor irrevocably and unconditionally and to the fullest extent permitted by law, waives, and agrees not to plead or claim, any immunity from jurisdiction of any court or
from any legal process (whether through service of notice, attachment prior to judgment, attachment in aid of execution, execution or otherwise) for itself, the Issuer or any of their property, assets or revenues wherever located with respect to its
obligations, liabilities or any other matter under or arising out of or in connection with this Amended and Restated Guaranty, any of the Transaction Documents or any document delivered pursuant hereto, in each case for the benefit of each assigns,
it being intended that the foregoing waiver and agreement will be effective, irrevocable and not subject to withdrawal in any and all jurisdictions, and, without limiting the generality of the foregoing, agrees that the waivers set forth in this
subsection (f) shall have the fullest scope permitted under the United States Foreign Sovereign Immunities Act of 1976 and are intended to be irrevocable for the purposes of such act. 

  
 17 

 SECTION 16. Execution in Counterparts. This Amended and Restated Guaranty and each
amendment, waiver and consent with respect hereto may be executed in any number of counterparts and by different parties thereto in separate counterparts, each of which when so executed shall be deemed to be an original and all of which taken
together shall constitute one and the same agreement. Delivery of an executed counterpart of a signature page to this Amended and Restated Guaranty by telecopier shall be effective as delivery of an original executed counterpart of this Amended and
Restated Guaranty. 
 SECTION 17. Entire Agreement. 

This Amended and Restated Guaranty, together with the Indenture and the 2021 Notes, sets forth the entire agreement of the parties hereto
with respect to the subject matter hereof.
