Ladies and Gentlemen:

Introductory. Syngenta Finance N.V., a limited liability company (naamloze vennootschap) organized under the laws of The Netherlands, and with corporate seat in Amsterdam, The Netherlands (the “Company”), proposes to issue and sell to the several underwriters named in Schedule A (the “Underwriters”), acting severally and not jointly, the respective amounts set forth in such Schedule A of $500,000,000 aggregate principal amount of the Company’s 3.125% Notes due March 28, 2022 (the “2022 Notes”) and $250,000,000 aggregate principal amount of the Company’s 4.375% Notes due March 28, 2042 (the “2042 Notes”) (the 2022 Notes and the 2042 Notes together, the “Notes”). The Notes will be fully and unconditionally guaranteed by Syngenta AG, a Swiss stock corporation (Aktiengesellschaft) organized under the laws of Switzerland (the “Guarantor”), as to payment of principal and interest (the “Guarantees”). Citigroup Global Markets Inc. (“Citigroup”) and Xxxxxxx Lynch, Xxxxxx, Xxxxxx & Xxxxx Incorporated (“Xxxxxxx Xxxxx”) have agreed to act as Underwriters (the “Underwriters”) in connection with the offering and sale of the Notes.

The Notes and the Guarantees will be issued pursuant to an indenture, dated as of March 28, 2012 (the “Base Indenture”), between the Company, the Guarantor and The Bank of New York Mellon, as trustee (the “Trustee”). Certain terms of the Notes will be established pursuant to an Officer’s Certificate to the Base Indenture (together with the Base Indenture, the “Indenture”). The Notes and the Guarantees will be issued in book-entry form in the name of Cede & Co., as nominee of The Depository Trust Company (the “Depositary”), pursuant to a Letter of Representations, to be dated on or before the Closing Date (as defined in Section 2 below) (the “DTC Agreement”), among the Company, the Guarantor, the Trustee and the Depositary.

The Company and the Guarantor have prepared and filed with the Securities and Exchange Commission (the “Commission”) a registration statement on Form F-3 (File No. 178015), which contains a base prospectus (the “Base Prospectus”), to be used in connection with the public offering and sale of debt securities, including the Notes and the Guarantees under the Securities Act of 1933, as amended, and the rules and regulations promulgated thereunder (collectively, the “Securities Act”), and the offering thereof from time to time in accordance with

Rule 415 under the Securities Act. Such registration statement, including the financial statements, exhibits and schedules thereto, in the form in which it became effective under the Securities Act, including any required information deemed to be a part thereof at the time of effectiveness pursuant to Rule 430B under the Securities Act, is called the “Registration Statement.” The term “Prospectus” shall mean the final prospectus supplement relating to the Notes, together with the Base Prospectus, that is first filed pursuant to Rule 424(b) after the date and time that this Agreement is executed (the “Execution Time”) by the parties hereto. The term “Preliminary Prospectus” shall mean any preliminary prospectus supplement relating to the Notes, together with the Base Prospectus, that is first filed with the Commission pursuant to Rule 424(b). Any reference herein to the Registration Statement, the Preliminary Prospectus or the Prospectus shall be deemed to refer to and include the documents that are or are deemed to be incorporated by reference therein pursuant to Item 6 of Form F-3 under the Securities Act prior to 8:09 p.m. London time on March 21, 2012 (the “Initial Sale Time”). All references in this Agreement to the Registration Statement, the Preliminary Prospectus, the Prospectus, or any amendments or supplements to any of the foregoing, shall include any copy thereof filed with the Commission pursuant to its Electronic Data Gathering, Analysis and Retrieval System (“XXXXX”).

All references in this Agreement to financial statements and schedules and other information which is “contained,” “included” or “stated” (or other references of like import) in the Registration Statement, the Prospectus or the Preliminary Prospectus shall be deemed to mean and include all such financial statements and schedules and other information which is or is deemed to be incorporated by reference in the Registration Statement, the Prospectus or the Preliminary Prospectus, as the case may be, prior to the Initial Sale Time; and all references in this Agreement to amendments or supplements to the Registration Statement, the Prospectus or the Preliminary Prospectus shall be deemed to include the filing of any document under the Securities Exchange Act of 1934, as amended, and the rules and regulations promulgated thereunder (collectively, the “Exchange Act”), which is or is deemed to be incorporated by reference in the Registration Statement, the Prospectus or the Preliminary Prospectus, as the case may be, after the Initial Sale Time.

Each of the Company and the Guarantor hereby confirms its agreements with the Underwriters as follows:

Section 1. Representations and Warranties of the Company and the Guarantor

Each of the Company and the Guarantor hereby jointly and severally represents, warrants and covenants to each Underwriter as of the date hereof, as of the Initial Sale Time and as of the Closing Date (in each case, a “Representation Date”), as follows:

a) Compliance with Registration Requirements. Each of the Company and the Guarantor meets the requirements for use of Form F-3 under the Securities Act. The Registration Statement has become effective under the Securities Act and no stop order suspending the effectiveness of the Registration Statement has been issued under the Securities Act and no proceedings for that purpose have been instituted or are pending or, to the best of each of the Company’s and the Guarantor’s knowledge, are contemplated or threatened by the Commission, and any request on the part of the Commission for additional information has been

complied with. In addition, the Indenture has been duly qualified under the Trust Indenture Act of 1939, as amended, and the rules and regulations promulgated thereunder (the “Trust Indenture Act”).

At the respective times the Registration Statement and any post-effective amendments thereto became effective and at each Representation Date, the Registration Statement and any amendments thereto (i) complied and will comply in all material respects with the requirements of the Securities Act, and (ii) did not and will not contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading. At the date of the Prospectus and at the Closing Date, neither the Prospectus nor any amendments or supplements thereto included or will include an untrue statement of a material fact or omitted or will omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading. Notwithstanding the foregoing, the representations and warranties in this subsection shall not apply to (i) statements in or omissions from the Registration Statement or any post-effective amendment or the Prospectus or any amendments or supplements thereto made in reliance upon and in conformity with information furnished to the Company and the Guarantor in writing by any of the Underwriters expressly for use therein, it being understood and agreed that the only such information furnished by any Underwriter consists of the information described as such in Section 8 hereof and (ii) that part of the Registration Statement that constitutes the Statement of Eligibility (Form T-1) under the Trust Indenture Act of the Trustee.

Each Preliminary Prospectus and the Prospectus, at the time each was filed with the Commission, complied in all material respects with the Securities Act, and the Preliminary Prospectus and the Prospectus delivered to the Underwriters for use in connection with the offering of the Notes will, at the time of such delivery, be identical to any electronically transmitted copies thereof filed with the Commission pursuant to XXXXX, except to the extent permitted by Regulation S-T.

b) Disclosure Package. The term “Disclosure Package” shall mean (i) the Preliminary Prospectus dated March 21, 2012, (ii) the issuer free writing prospectuses as defined in Rule 433 of the Securities Act (each, an “Issuer Free Writing Prospectus”), if any, identified in Annex I hereto and (iii) any other free writing prospectus that the parties hereto shall hereafter expressly agree in writing to treat as part of the Disclosure Package. As of the Initial Sale Time, the Disclosure Package did not contain any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading. The preceding sentence does not apply to statements in or omissions from the Disclosure Package based upon and in conformity with written information furnished to the Company and the Guarantor by any Underwriter specifically for use therein, it being understood and agreed that the only such information furnished by any Underwriter consists of the information described as such in Section 8 hereof.

c) Incorporated Documents. The documents incorporated or deemed to be incorporated by reference in the Registration Statement, the Preliminary Prospectus and the Prospectus (i) at the time they were or hereafter are filed with the Commission, complied or will comply in all material respects with the requirements of the Exchange Act and (ii) when read together with the other information in the Disclosure Package, at the Initial Sale Time, and when

read together with the other information in the Prospectus, at the date of the Prospectus and at the Closing Date, did not or will not include an untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading.

d) The Guarantor is a Well-Known Seasoned Issuer. (i) At the time of filing the Registration Statement, (ii) at the time of the most recent amendment thereto for the purposes of complying with Section 10(a)(3) of the Securities Act (whether such amendment was by post-effective amendment, incorporated report filed pursuant to Section 13 or 15(d) of the Exchange Act or form of prospectus), (iii) at the time the Company, the Guarantor or any person acting on their behalf (within the meaning, for this clause only, of Rule 163(c) of the Securities Act) made any offer relating to the Notes or the Guarantees in reliance on the exemption of Rule 163 of the Securities Act, and (iv) as of the Execution Time, the Guarantor was and is a “well known seasoned issuer” as defined in Rule 405 of the Securities Act. The Registration Statement is an “automatic shelf registration statement,” as defined in Rule 405 of the Securities Act, that automatically became effective not more than three years prior to the Execution Time; neither the Company nor the Guarantor has received from the Commission any notice pursuant to Rule 401(g)(2) of the Securities Act objecting to use of the automatic shelf registration statement form and neither the Company nor the Guarantor has otherwise ceased to be eligible to use the automatic shelf registration form.

e) Not an Ineligible Issuer. (i) At the time of filing the Registration Statement and (ii) as of the Execution Time (with such date being used as the determination date for purposes of this clause (ii)), each of the Company and the Guarantor was not and is not an Ineligible Issuer (as defined in Rule 405 of the Securities Act), without taking account of any determination by the Commission pursuant to Rule 405 of the Securities Act that it is not necessary that each of the Company and the Guarantor be considered an Ineligible Issuer.

f) Issuer Free Writing Prospectuses. Each Issuer Free Writing Prospectus, as of its issue date and at all subsequent times through the completion of the offering of Notes and the Guarantees under this Agreement or until any earlier date that the Company or the Guarantor notified or notifies the Underwriters as described in the next sentence, did not, does not and will not include any information that conflicted, conflicts or will conflict with the information contained in the Registration Statement, the Preliminary Prospectus or the Prospectus. If at any time following issuance of an Issuer Free Writing Prospectus there occurred or occurs an event or development as a result of which such Issuer Free Writing Prospectus conflicted or would conflict with the information contained in the Registration Statement, the Preliminary Prospectus or the Prospectus the Company or the Guarantor has promptly notified or will promptly notify the Underwriters and has promptly amended or supplemented or will promptly amend or supplement, at its own expense, such Issuer Free Writing Prospectus to eliminate or correct such conflict. The foregoing two sentences do not apply to statements in or omissions from any Issuer Free Writing Prospectus based upon and in conformity with written information furnished to the Company and the Guarantor by any Underwriter specifically for use therein, it being understood and agreed that the only such information furnished by any Underwriter consists of the information described as such in Section 8 hereof.

g) Distribution of Offering Material By the Company and the Guarantor. Each of the Company and the Guarantor has not distributed and will not distribute, prior to the later of the Closing Date and the completion of the Underwriters’ distribution of the Notes, any offering material in connection with the offering and sale of the Notes other than the Registration Statement, the Preliminary Prospectus, the Prospectus, any Issuer Free Writing Prospectus reviewed and consented to by the Underwriters and included in Annex I hereto or any electronic road show or other written communications reviewed and consented to by the Underwriters and listed on Xxxxx XX hereto (each an, “Additional Written Communication”). Each such Additional Written Communication, when taken together with the Disclosure Package, did not, and at the Closing Date will not, contain any untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading. The preceding sentence does not apply to statements in or omissions from the Additional Written Communication based upon and in conformity with written information furnished to the Company and the Guarantor by any Underwriter specifically for use therein, it being understood and agreed that the only such information furnished by any Underwriter consists of the information described as such in Section 8 hereof.

h) No Applicable Registration or Other Similar Rights. There are no persons with registration or other similar rights to have any equity or debt securities registered for sale under the Registration Statement or included in the offering contemplated by this Agreement, except for such rights as have been duly waived.

i) The Underwriting Agreement. This Agreement has been duly authorized, executed and delivered by each of the Company and the Guarantor.

j) Authorization of the Indenture. The Indenture has been duly qualified under the Trust Indenture Act and has been duly authorized, and at the Closing Date will have been duly executed and delivered by each of the Company and the Guarantor and will constitute a valid and binding agreement of each of the Company and the Guarantor, enforceable against each of the Company and the Guarantor in accordance with its terms, except as the enforcement thereof may be limited by bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium or other similar laws relating to or affecting the rights and remedies of creditors or by general equitable principles.

k) Authorization of the Notes. The Notes to be purchased by the Underwriters from the Company are in the form contemplated by the Indenture, have been duly authorized for issuance and sale pursuant to this Agreement and the Indenture and, at the Closing Date, will have been duly executed by the Company and, when authenticated in the manner provided for in the Indenture and delivered against payment of the purchase price therefor, will constitute valid and binding obligations of the Company, enforceable in accordance with their terms, except as the enforcement thereof may be limited by bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium or other similar laws relating to or affecting the rights and remedies of creditors or by general equitable principles, and will be entitled to the benefits of the Indenture.

l) Authorization of the Guarantees. The Guarantees are in the form contemplated by the Indenture, have been duly authorized for issuance and sale pursuant to this Agreement and

the Indenture and, at the Closing Date, will have been duly executed by the Guarantor and, when the Notes have been authenticated in the manner provided for in the Indenture and duly endorsed, will constitute a valid and binding obligation of the Guarantor, enforceable in accordance with their terms, except as the enforcement thereof may be limited by bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium or other similar laws relating to or affecting the rights and remedies of creditors or by general equitable principles, and will be entitled to the benefits of the Indenture.

o) No Material Adverse Change. Except as otherwise disclosed in the Disclosure Package, subsequent to the respective dates as of which information is given in the Disclosure Package, there has been no material adverse change, or any development that could reasonably be expected to result in a material adverse change, in the condition, financial or otherwise, or in the earnings, business, operations or prospects, whether or not arising from transactions in the ordinary course of business, of the Guarantor and the Guarantor’s subsidiaries, considered together as one entity (any such change is called a “Material Adverse Change”).

Xxxxx & Young AG, who have expressed their opinion with respect to the Guarantor’s audited financial statements for the fiscal years ended December 31, 2011, 2010 and 2009 incorporated by reference in the Registration Statement, the Preliminary Prospectus and the Prospectus, are independent public accountants with respect to the Company and the Guarantor as required by the Securities Act and the Exchange Act and are an independent registered public accounting firm with the Public Company Accounting Oversight Board.

The financial statements together with the related notes thereto incorporated by reference in the Registration Statement, the Preliminary Prospectus and the Prospectus present fairly the consolidated financial position of the Guarantor and its subsidiaries as of and at the dates indicated and the results of their operations and cash flows for the periods specified. Such financial statements comply as to form with the accounting requirements of the Securities Act and have been prepared in conformity with International Financial Reporting Standards as issued by the International Accounting Standards Board (“IFRS”) applied on a consistent basis throughout the periods involved, except as may be expressly stated in the related notes thereto.

As used herein, a “Debt Repayment Triggering Event” means any event or condition which gives, or with the giving of notice or lapse of time or both would give, the holder of any note, debenture or other evidence of indebtedness (or any person acting on such holder’s behalf) issued by the Company or the Guarantor or any of the Guarantor’s Significant Subsidiaries, the right to require the repurchase, redemption or repayment of all or a portion of such indebtedness by the Company or the Guarantor or any of the Guarantor’s Significant Subsidiaries.

x) Title to Properties. The Guarantor and its subsidiaries have good and marketable title to, or have valid rights to lease or otherwise use, all items of real property, equipment and personal property that are material to the respective businesses of the Guarantor and its subsidiaries, in each case free and clear of all security interests, mortgages, liens, encumbrances, claims and defects and imperfections of title except those that (i) do not materially interfere with the use made and proposed to be made of such property by the Guarantor and its subsidiaries or (ii) would not, individually or in the aggregate, have a Material Adverse Effect.

y) Tax Law Compliance. Each of the Company and the Guarantor have filed all the required income tax returns in a timely manner and have paid all taxes required to be paid by any of them and, if due and payable, any related or similar assessment, fine or penalty levied against any of them, except for any taxes, assessments, fines or penalties as may be being contested in good faith and by appropriate proceedings, except where a default to make such filings or payments would not, individually or in the aggregate, have a Material Adverse Effect. The Guarantor has made appropriate provisions in the applicable financial statements referred to in Section 1(q) above in respect of all income taxes for all current or prior periods as to which the tax liability of the Guarantor or any of its Significant Subsidiaries has not been finally determined.

z) Company and Guarantor Not Investment Companies.

a) Compliance with Securities Regulations and Commission Requests. Each of the Company and the Guarantor, subject to Section 3(b), will comply with the requirements of Rule 430B of the Securities Act, and will promptly notify the Underwriters, and confirm the notice in writing, of (i) the effectiveness during the Prospectus Delivery Period (as defined below) of any post-effective amendment to the Registration Statement or the filing of any supplement or amendment to the Preliminary Prospectus or the Prospectus, (ii) the receipt of any

Each of the Company and the Guarantor will promptly effect the filings necessary pursuant to Rule 424 and will take such steps as it deems necessary to ascertain promptly whether the Preliminary Prospectus and the Prospectus transmitted for filing under Rule 424 was received for filing by the Commission and, in the event that it was not, it will promptly file such document. Each of the Company and the Guarantor will use its reasonable best efforts to prevent the issuance of any stop order and, if any stop order is issued, to obtain the lifting thereof at the earliest possible moment.

b) Filing of Amendments. During such period beginning on the date of this Agreement and ending on the later of the Closing Date or such date as, in the opinion of counsel for the Underwriters, the Prospectus is no longer required by law to be delivered in connection with sales of the Notes by an Underwriter or dealer, including in circumstances where such requirement may be satisfied pursuant to Rule 172 of the Securities Act (the “Prospectus Delivery Period”), each of the Company and the Guarantor will give the Underwriters notice of its intention to file or prepare any amendment to the Registration Statement (including any filing under Rule 462(b) of the Securities Act), or any amendment, supplement or revision to the Disclosure Package or the Prospectus, whether pursuant to the Securities Act, the Exchange Act or otherwise, will furnish the Underwriters with copies of any such documents a reasonable amount of time prior to such proposed filing or use, as the case may be, and will not file or use any such document to which the Underwriters or counsel for the Underwriters shall reasonably object.

c) Delivery of Registration Statements. The Company or the Guarantor has furnished or will deliver to the Underwriters and counsel for the Underwriters, without charge, signed copies of the Registration Statement as originally filed and of each amendment thereto (including exhibits filed therewith or incorporated by reference therein and documents incorporated or deemed to be incorporated by reference therein) and signed copies of all consents and certificates of experts, and will also deliver to the Underwriters, without charge, a conformed copy of the Registration Statement as originally filed and of each amendment thereto (without exhibits) for each of the Underwriters.

If at any time during the Prospectus Delivery Period, any event shall occur or condition shall exist as a result of which it is necessary, in the opinion of counsel for the Underwriters or for the Company and the Guarantor, to amend the Registration Statement in order that the Registration Statement will not contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading or to amend or supplement the Disclosure Package or the Prospectus in order that the Disclosure Package or the Prospectus, as the case may be, will not include an untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances existing at the Initial Sale Time or at the time it is delivered or conveyed to a purchaser, not misleading, or if it shall be necessary, in the opinion of either such counsel, at any such time to amend the Registration Statement or amend or supplement the Disclosure Package or the Prospectus in order to comply with the requirements of any law, the Company and the Guarantor will (1) notify the Underwriters of any such event, development or condition and (2) promptly prepare and file with the Commission, subject to Section 3(b) hereof, such amendment or supplement as may be necessary to correct such statement or omission or to make the Registration Statement, the Disclosure Package or the Prospectus comply with such law, and the Company and the Guarantor will furnish to the Underwriters, without charge, such number of copies of such amendment or supplement as the Underwriters may reasonably request.

Each of the Company and the Guarantor shall cooperate with the Underwriters and counsel for the Underwriters to qualify or register the Notes and the Guarantees for sale under (or obtain exemptions from the application of) the state securities or blue sky laws of those jurisdictions designated by the Underwriters, shall comply with such laws and shall continue such qualifications, registrations and exemptions in effect so long as required for the distribution of the Notes and the Guarantees. The Company and the Guarantor shall not be required to qualify to transact business or to take any action that would subject it to general service of process in any such jurisdiction where it is not presently qualified or where it would be subject to taxation as a foreign business.

The Company will prepare a final term sheet containing only a description of the Notes, in a form approved by the Underwriters and attached as Exhibit D hereto, and will file such term sheet pursuant to Rule 433(d) under the Securities Act within the time required by such rule (such term sheet, the “Final Term Sheet”). Any such Final Term Sheet is an Issuer Free Writing Prospectus for purposes of this Agreement.

l) Permitted Free Writing Prospectuses. Each of the Company and the Guarantor represents that it has not made, and agrees that, unless it obtains the prior written consent of the Underwriters, it will not make, any offer relating to the Notes that would constitute an Issuer Free Writing Prospectus or that would otherwise constitute a “free writing prospectus” (as defined in Rule 405 of the Securities Act) required to be filed by the Company or the Guarantor with the Commission or retained by the Company or the Guarantor under Rule 433 of the Securities Act; provided that the prior written consent of the Underwriters shall be deemed to have been given in respect of any Issuer Free Writing Prospectuses included in Annex I to this Agreement. Any such free writing prospectus consented to or deemed to be consented to by the Underwriters is hereinafter referred to as a “Permitted Free Writing Prospectus.” Each of the Company and the Guarantor agrees that (i) it has treated and will treat, as the case may be, each Permitted Free Writing Prospectus as an Issuer Free Writing Prospectus, and (ii) has complied and will comply, as the case may be, with the requirements of Rules 164 and 433 of the Securities Act applicable to any Permitted Free Writing Prospectus, including in respect of timely filing with the Commission, legending and record keeping. Each of the Company and the Guarantor consents to the use by any Underwriter of a free writing prospectus that (a) is not an “issuer free writing prospectus” as defined in Rule 433, and (b) contains only (i) information describing the preliminary terms of the Notes and the Guarantees or their offering, (ii) information permitted by Rule 134 under the Securities Act or (iii) information that describes the final terms of the Notes and the Guarantees or their offering and that is included in the Final Term Sheet of the Company contemplated in Section 3(k).

m) Notice of Inability to Use Automatic Shelf Registration Statement Form. If at any time during the Prospectus Delivery Period, either the Company or the Guarantor receives from the Commission a notice pursuant to Rule 401(g)(2) or otherwise ceases to be eligible to use the automatic shelf registration statement form, the Company or the Guarantor, as applicable, will (i) promptly notify the Underwriters, (ii) promptly file a new registration statement or post-effective amendment on the proper form relating to the Notes and the Guarantees, in a form satisfactory to the Underwriters, (iii) use its best efforts to cause such registration statement of post-effective amendment to be declared effective and (iv) promptly notify the Underwriters of such effectiveness. Each of the Company and the Guarantor will take all other action necessary or appropriate to permit the public offering and sale of the Notes and the Guarantees to continue as contemplated in the registration statement that was the subject of the Rule 401(g)(2) notice or for which the Company or the Guarantor has otherwise become ineligible. References herein to the Registration Statement shall include such new registration statement or post-effective amendment, as the case may be.

n) Filing Fees. The Company agrees to pay the required Commission filing fees relating to the Notes within the time required by and in accordance with Rule 456(b)(1) and 457(r) of the Securities Act.

o) No Manipulation of Price. Each of the Company and the Guarantor will not take, directly or indirectly, any action designed to cause or result in, or that has constituted or might reasonably be expected to constitute, under the Exchange Act or otherwise, the stabilization or manipulation of the price of any securities of the Company or the Guarantor to facilitate the sale or resale of the Notes or the Guarantees.

The Underwriters, may, in their sole discretion, waive in writing the performance by the Company or the Guarantor of any one or more of the foregoing covenants or extend the time for their performance.

Promptly after receipt by an indemnified party under this Section 8 of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against an indemnifying party under this Section 8, notify the indemnifying party in writing of the commencement thereof, but the omission so to notify the indemnifying party will not relieve it from any liability which it may have to any indemnified party for contribution or otherwise than under the indemnity agreement contained in this Section 8 or to the extent it is not prejudiced as a proximate result of such failure. In case any such action is brought against any indemnified party and such indemnified party seeks or intends to seek indemnity from an indemnifying party, the indemnifying party will be entitled to participate in, and, to the extent that it shall elect, jointly with all other indemnifying parties similarly notified, by written notice delivered to the

indemnified party, to assume the defense thereof with counsel reasonably satisfactory to such indemnified party; provided, however, such indemnified party shall have the right to employ its own counsel in any such action and to participate in the defense thereof, but the fees and expenses of such counsel shall be at the expense of such indemnified party, unless: (i) the employment of such counsel has been specifically authorized in writing by the indemnifying party; (ii) the indemnifying party has failed promptly to assume the defense and employ counsel reasonably satisfactory to the indemnified party; or (iii) the named parties to any such action (including any impleaded parties) include both such indemnified party and the indemnifying party or any affiliate of the indemnifying party, and such indemnified party shall have reasonably concluded that either (x) there may be one or more legal defenses available to it which are different from or additional to those available to the indemnifying party or such affiliate of the indemnifying party or (y) a conflict may exist between such indemnified party and the indemnifying party or such affiliate of the indemnifying party (it being understood, however, that the indemnifying party shall not, in connection with any one such action or separate but substantially similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances, be liable for the fees and expenses of more than one separate firm of attorneys (in addition to a single firm of local counsel) for all such indemnified parties, which firm shall be designated in writing by the Underwriters and that all such reasonable fees and expenses shall be reimbursed as they are incurred). Upon receipt of notice from the indemnifying party to such indemnified party of such indemnifying party’s election so to assume the defense of such action and approval by the indemnified party of counsel, the indemnifying party will not be liable to such indemnified party under this Section 8 for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof unless the indemnified party shall have employed separate counsel in accordance with the proviso to the next preceding sentence, in which case the reasonable fees and expenses of counsel shall be at the expense of the indemnifying party.

(d) Settlements. The indemnifying party under this Section 8 shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the indemnifying party agrees to indemnify the indemnified party against any loss, claim, damage, liability or expense by reason of such settlement or judgment. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement, compromise or consent to the entry of judgment in any pending or threatened action, suit or proceeding in respect of which any indemnified party is or could have been a party and indemnity was or could have been sought hereunder by such indemnified party, unless such settlement, compromise or consent (i) includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such action, suit or proceeding and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of any indemnified party.

Section 9. Contribution. If the indemnification provided for in Section 8 is for any reason held to be unavailable to or otherwise insufficient to hold harmless an indemnified party in respect of any losses, claims, damages, liabilities or expenses referred to therein, then each indemnifying party shall contribute to the aggregate amount paid or payable by such indemnified party, as incurred, as a result of any losses, claims, damages, liabilities or expenses referred to therein (i) in such proportion as is appropriate to reflect the relative benefits received by the Company or the Guarantor, on the one hand, and the Underwriters, on the other hand, from the

offering of the Notes and the Guarantees pursuant to this Agreement or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company or the Guarantor, on the one hand, and the Underwriters, on the other hand, in connection with the statements or omissions which resulted in such losses, claims, damages, liabilities or expenses, as well as any other relevant equitable considerations. The relative benefits received by the Company or the Guarantor, on the one hand, and the Underwriters, on the other hand, in connection with the offering of the Notes or the Guarantees pursuant to this Agreement shall be deemed to be in the same respective proportions as the total net proceeds from the offering of the Notes or the Guarantees pursuant to this Agreement (before deducting expenses) received by the Company or the Guarantor, and the total underwriting discount received by the Underwriters, in each case as set forth on the front cover page of the Prospectus bear to the aggregate initial public offering price of the Notes as set forth on such cover. The relative fault of the Company or the Guarantor, on the one hand, and the Underwriters, on the other hand, shall be determined by reference to, among other things, whether any such untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Company or the Guarantor, on the one hand, or the Underwriters, on the other hand, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

The amount paid or payable by a party as a result of the losses, claims, damages, liabilities and expenses referred to above shall be deemed to include, subject to the limitations set forth in Section 8(c), any reasonable legal or other fees or expenses reasonably incurred by such party in connection with investigating or defending any action or claim.

The Company and the Guarantor, on the one hand, and the Underwriters, on the other hand, agree that it would not be just and equitable if contribution pursuant to this Section 9 were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to in this Section 9.

Notwithstanding the provisions of this Section 9, no Underwriter shall be required to contribute any amount in excess of the underwriting commissions received by such Underwriter in connection with the Notes underwritten by it and distributed to the public. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ obligations to contribute pursuant to this Section 9 are several, and not joint, in proportion to their respective underwriting commitments as set forth opposite their names in Schedule A. For purposes of this Section 9, each director, officer, employee, affiliate and agent of an Underwriter and each person, if any, who controls an Underwriter within the meaning of the Securities Act and the Exchange Act shall have the same rights to contribution as such Underwriter, and each director of the Company or the Guarantor, each officer of the Company or the Guarantor who signed the Registration Statement, and each person, if any, who controls the Company or the Guarantor with the meaning of the Securities Act and the Exchange Act shall have the same rights to contribution as the Company and the Guarantor.

Section 10. Default of One or More of the Several Underwriters. If, on the Closing Date, any one or more of the several Underwriters shall fail or refuse to purchase Notes that it or they have agreed to purchase hereunder on such date, and the aggregate principal amount of Notes, which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase does not exceed 10% of the aggregate principal amount of the Notes to be purchased on such date, the other Underwriters shall be obligated, severally, in the proportion to the aggregate principal amounts of such Notes set forth opposite their respective names on Schedule A bears to the aggregate principal amount of such Notes set forth opposite the names of all such non-defaulting Underwriters, or in such other proportions as may be specified by the Underwriters with the consent of the non-defaulting Underwriters, to purchase such Notes which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase on such date. If, on the Closing Date, any one or more of the Underwriters shall fail or refuse to purchase such Notes and the aggregate principal amount of such Notes with respect to which such default occurs exceeds 10% of the aggregate principal amount of Notes to be purchased on such date, and arrangements satisfactory to the Underwriters and the Company for the purchase of such Notes are not made within 48 hours after such default, this Agreement shall terminate without liability of any party to any other party except that the provisions of Sections 4, 6, 8, 9 and 17 shall at all times be effective and shall survive such termination. In any such case, either the Underwriters or the Company shall have the right to postpone the Closing Date, but in no event for longer than seven days in order that the required changes, if any, to the Registration Statement, any Issuer Free Writing Prospectus, the Preliminary Prospectus or the Prospectus or any other documents or arrangements may be effected.

As used in this Agreement, the term “Underwriter” shall be deemed to include any person substituted for a defaulting Underwriter under this Section 10. Any action taken under this Section 10 shall not relieve any defaulting Underwriter from liability in respect of any default of such Underwriter under this Agreement.

Section 11. Termination of this Agreement. Prior to the Closing Date, this Agreement may be terminated by the Underwriters by notice given to the Company or the Guarantor if at any time (i) trading or quotation in any of the Company’s or the Guarantor’s securities shall have been suspended or limited by the Commission, the SIX Swiss Exchange or the New York Stock Exchange, or trading in securities generally on either the Nasdaq Stock Market, the New York Stock Exchange or the SIX Swiss Exchange shall have been suspended or limited, or minimum or maximum prices shall have been generally established on any of such stock exchanges by the Commission or the FINRA; (ii) a general banking moratorium shall have been declared by any Swiss, United States federal or New York authorities; (iii) there shall have occurred any outbreak or escalation of national or international hostilities or any crisis or calamity involving Switzerland, the United States, or any change in the United States, Swiss or international financial markets, or any substantial change or development involving a prospective substantial change in Swiss, United States or international political, financial or economic conditions, as in the reasonable judgment of the Underwriters is material and adverse and makes it impracticable or inadvisable to market the Notes in the manner and on the terms described in the Disclosure Package or the Prospectus or to enforce contracts for the sale of securities; (iv) in the reasonable judgment of the Underwriters there shall have occurred any Material Adverse Change; or (v) there shall have occurred a material disruption in commercial banking or securities settlement or clearance services in the jurisdictions where the Notes are offered. Any termination pursuant to

this Section 11 shall be without liability of any party to any other party except as provided in Sections 4 and 6 hereof, and provided further that Sections 4, 6, 8, 9 and 17 shall survive such termination and remain in full force and effect.

Section 12. No Fiduciary Duty. Each of the Company and the Guarantor acknowledges and agrees that: (i) the purchase and sale of the Notes and the Guarantees pursuant to this Agreement, including the determination of the public offering price of the Notes and the Guarantees and any related discounts and commissions, is an arm’s-length commercial transaction between the Company and the Guarantor, on the one hand, and the several Underwriters, on the other hand, and each of the Company and the Guarantor is capable of evaluating and understanding and understands and accepts the terms, risks and conditions of the transactions contemplated by this Agreement; (ii) in connection with each transaction contemplated hereby and the process leading to such transaction each Underwriter is and has been acting solely as a principal and is not the financial advisor, agent or fiduciary of the Company or the Guarantor or their affiliates, stockholders, creditors or employees or any other party; (iii) no Underwriter has assumed or will assume an advisory, agency or fiduciary responsibility in favor of the Company or the Guarantor with respect to any of the transactions contemplated hereby or the process leading thereto (irrespective of whether such Underwriter has advised or is currently advising the Company or the Guarantor on other matters) and no Underwriter has any obligation to the Company or the Guarantor with respect to the offering contemplated hereby except the obligations expressly set forth in this Agreement; (iv) the several Underwriters and their respective affiliates may be engaged in a broad range of transactions that involve interests that differ from those of the Company or the Guarantor and that the several Underwriters have no obligation to disclose any of such interests by virtue of any advisory, agency or fiduciary relationship; and (v) the Underwriters have not provided any legal, accounting, regulatory or tax advice with respect to the offering contemplated hereby and each of the Company and the Guarantor has consulted its own legal, accounting, regulatory and tax advisors to the extent it deemed appropriate.

This Agreement supersedes all prior agreements and understandings (whether written or oral) between the Company and the Guarantor, on the one hand, and the several Underwriters, on the other hand, with respect to the subject matter hereof. Each of the Company and the Guarantor hereby waives and releases, to the fullest extent permitted by law, any claims that each of the Company and the Guarantor may have against the several Underwriters with respect to any breach or alleged breach of agency or fiduciary duty.

Section 13. Representations and Indemnities to Survive Delivery. The respective indemnities, agreements, representations, warranties and other statements of each of the Company and the Guarantor, of their officers and of the several Underwriters set forth in or made pursuant to this Agreement (i) will remain operative and in full force and effect, regardless of any (A) investigation, or statement as to the results thereof, made by or on behalf of any Underwriter, the officers or employees of any Underwriter, or any person controlling the Underwriter, the Company or the Guarantor, the officers or employees of the Company or the Guarantor, or any person controlling the Company or the Guarantor, as the case may be or (B) acceptance of the Notes and payment for them hereunder and (ii) will survive delivery of and payment for the Notes sold hereunder and any termination of this Agreement.

Section 15. Successors. This Agreement will inure to the benefit of and be binding upon the parties hereto, including any substitute Underwriters pursuant to Section 10 hereof, and to the benefit of the directors, officers, employees, affiliates, agents and controlling persons referred to in Sections 8 and 9, and in each case their respective successors, and no other person will have any right or obligation hereunder. The term “successors” shall not include any purchaser of the Notes as such from any of the Underwriters merely by reason of such purchase.

Section 16. Partial Unenforceability. The invalidity or unenforceability of any Section, paragraph or provision of this Agreement shall not affect the validity or enforceability of any other Section, paragraph or provision hereof. If any Section, paragraph or provision of this Agreement is for any reason determined to be invalid or unenforceable, there shall be deemed to be made such minor changes (and only such minor changes) as are necessary to make it valid and enforceable.

Section 17. Governing Law Provisions. THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED AND INTERPRETED IN ACCORDANCE WITH, THE INTERNAL LAWS OF THE STATE OF NEW YORK APPLICABLE TO AGREEMENTS MADE AND TO BE PERFORMED IN THAT STATE.

(a) Consent to Jurisdiction. Any legal suit, action or proceeding arising out of or based upon this Agreement or the transactions contemplated hereby (“Related Proceedings”) may be instituted in the federal courts of the United States of America located in the City and County of New York, Borough of Manhattan, or the courts of the State of New York in each case located in the City and County of New York, Borough of Manhattan (collectively, the “Specified Courts”), and each party irrevocably submits to the exclusive jurisdiction (except for proceedings instituted in regard to the enforcement of a judgment of any such court (a “Related Judgment”), as to which such jurisdiction is non-exclusive) of such courts in any such suit, action or proceeding. Service of any process, summons, notice or document by mail to such party’s address set forth above shall be effective service of process for any suit, action or other proceeding brought in any such court. The parties irrevocably and unconditionally waive any objection to the laying of venue of any suit, action or other proceeding in the Specified Courts and irrevocably and unconditionally waive and agree not to plead or claim in any such court that any such suit, action or other proceeding brought in any such court has been brought in an inconvenient forum. Each of the Company and the Guarantor appoints CT Corporation System, acting through its office at 000 Xxxxxx Xxxxxx, 00xx Xxxxx, Xxx Xxxx, XX 00000, as its agent to receive service of process

or other legal summons for purposes of any such suit, action or proceeding that may be instituted in any state or federal court in the City and County of New York.

(b) Waiver of Immunity. With respect to any Related Proceeding, each party irrevocably waives, to the fullest extent permitted by applicable law, all immunity (whether on the basis of sovereignty or otherwise) from jurisdiction, service of process, attachment (both before and after judgment) and execution to which it might otherwise be entitled in the Specified Courts, and with respect to any Related Judgment, each party waives any such immunity in the Specified Courts or any other court of competent jurisdiction, and will not raise or claim or cause to be pleaded any such immunity at or in respect of any such Related Proceeding or Related Judgment, including, without limitation, any immunity pursuant to the United States Foreign Sovereign Immunities Act of 1976, as amended.

Section 18. Other Relationships, Research Analyst Independence. Each of the Company and the Guarantor acknowledges that each of the Underwriters is a full service securities firm and as such, in the ordinary course of their business activities, each of the Underwriters and their affiliates may make or hold a broad array of investments and actively trade debt and equity securities (or related derivative securities) and financial instruments (including bank loans) for their own account and for the accounts of their customers. Such investments and securities activities may involve securities and/or instruments of the Company or the Guarantor or their affiliates. Certain of the Underwriters or their affiliates that have a lending relationship with the Company or the Guarantor routinely hedge their credit exposure to the Company or the Guarantor, consistent with their customary risk management policies. Typically, such Underwriters and their affiliates would hedge such exposure by entering into transactions which consist of either the purchase of credit default swaps or the creation of short positions in securities, including potentially the notes. Any such short positions could adversely affect future trading prices of the Notes and the related Guarantee. Each of the Company and the Guarantor acknowledges that the Underwriters and their affiliates may also make investment recommendations and/or publish or express independent research views in respect of such securities or financial instruments and may hold, or recommend to clients that they acquire, long and/or short positions in such securities and instruments.

Section 19. General Provisions. This Agreement may be executed in two or more counterparts, each one of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument. This Agreement may not be amended or modified unless in writing by all of the parties hereto, and no condition herein (express or implied) may be waived unless waived in writing by each party whom the condition is meant to benefit. The Section headings herein are for the convenience of the parties only and shall not affect the construction or interpretation of this Agreement.

Each of the parties hereto acknowledges that it is a sophisticated business person who was adequately represented by counsel during negotiations regarding the provisions hereof, including, without limitation, the indemnification provisions of Section 8 and the contribution provisions of Section 9, and is fully informed regarding said provisions. Each of the parties hereto further acknowledges that the provisions of Sections 8 and 9 hereto fairly allocate the risks in light of the ability of the parties to investigate each of the Company and the Guarantor, its affairs and its business in order to assure that adequate disclosure has been made in the

Registration Statement, the Disclosure Package and the Prospectus (and any amendments and supplements thereto), as required by the Securities Act and the Exchange Act.

If the foregoing is in accordance with your understanding of our agreement, kindly sign and return to the Company and the Guarantor the enclosed copies hereof, whereupon this instrument, along with all counterparts hereof, shall become a binding agreement in accordance with its terms.

Very truly yours, SYNGENTA FINANCE N.V.
