To the Managers named in Schedule I hereto

for the Underwriters named in Schedule II hereto

Ladies and Gentlemen:

Covidien International Finance S.A., a Luxembourg public limited liability company (the “Company”), proposes to issue and sell to the several underwriters named in Schedule II hereto (the “Underwriters”), for whom you are acting as managers (the “Managers”), the principal amount of its debt securities identified in Schedule I hereto (the “Securities”). The Securities will be fully and unconditionally guaranteed as to payment of principal, premium, if any, and interest (the “Guarantees”) by Covidien Ltd., a Bermuda company, and Covidien public limited company (“Covidien plc”), an Irish public limited company (collectively, the “Guarantors”). The Securities and the Guarantees are to be issued under the indenture, dated as of October 22, 2007 (the “Base Indenture”), as subsequently supplemented (the Base Indenture as so supplemented, the “Indenture”) among the Company, the Guarantors, and Deutsche Bank Trust Company Americas, as trustee (the “Trustee”). If the firm or firms listed in Schedule II hereto include only the Managers listed in Schedule I hereto, then the terms “Underwriters” and “Managers” as used herein shall each be deemed to refer to such firm or firms.

The Company and the Guarantors have filed with the Securities and Exchange Commission (the “Commission”) a registration statement, including a prospectus, (the file number of which is set forth in Schedule I hereto) on Form S-3, relating to securities (the “Shelf Securities”) to be issued from time to time by the Company and the Guarantors. The registration statement as amended to the date of this Agreement, including the information (if any) deemed to be part of the registration statement at the time of effectiveness pursuant to Rule 430A or Rule 430B under the Securities Act of 1933, as amended (the “Securities Act”), is hereinafter referred to as the “Registration Statement,” and the related prospectus covering the Shelf Securities dated June 21, 2010 in the form first used to confirm sales of the Securities (or in the form first made available to the Underwriters by the Company and the Guarantors to meet requests of purchasers pursuant to Rule 173 under the Securities Act) is hereinafter referred to as the “Basic Prospectus.” The Basic Prospectus, as supplemented by the prospectus supplement specifically relating to the Securities in the form first used to confirm sales of the Securities (or in the form first made available to the Underwriters by the Company or the Guarantors to meet requests of purchasers pursuant to Rule 173 under the Securities Act) is hereinafter referred to as the “Prospectus,” and the term “preliminary prospectus” means any preliminary form of the Prospectus. For purposes of this Agreement, “free writing prospectus” has the meaning set forth in Rule 405 under the Securities Act, “Time of Sale

Prospectus” means the Prospectus most recently available prior to when sales of the Securities were first made, together with the free writing prospectuses, if any, each identified in Schedule I hereto, and “broadly available road show” means a “bona fide electronic road show” as defined in Rule 433(h)(5) under the Securities Act that has been made available without restriction to any person. As used herein, the terms “Registration Statement,” “Basic Prospectus,” “preliminary prospectus,” “Time of Sale Prospectus” and “Prospectus” shall include the documents, if any, incorporated by reference therein. The terms “supplement,” “amendment,” and “amend” as used herein with respect to the Registration Statement, the Basic Prospectus, the Time of Sale Prospectus, any preliminary prospectus or free writing prospectus shall include all documents subsequently filed by the Company and the Guarantors with the Commission pursuant to the Securities Exchange Act of 1934, as amended (the “Exchange Act”), that are deemed to be incorporated by reference therein.

thereunder, (v) the Time of Sale Prospectus does not, and at the time of each sale of the Securities in connection with the offering when the Prospectus is not yet available to prospective purchasers and at the Closing Date (as defined in Section 4), the Time of Sale Prospectus, as then amended or supplemented by the Company and the Guarantors, if applicable, will not, contain any untrue statement of a material fact or omit to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, (vi) each broadly available road show, if any, when considered together with the Time of Sale Prospectus, does not contain any untrue statement of a material fact or omit to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, (vii) on the date hereof and on the Closing Date, the Indenture did or will comply in all material respects with the applicable requirements of the Trust Indenture Act of 1939, as amended (the “Trust Indenture Act”) and the rules thereunder, and (viii) the Prospectus does not contain and, as amended or supplemented, if applicable, will not contain any untrue statement of a material fact or omit to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, except that the representations and warranties set forth in this paragraph do not apply to (x) statements or omissions in the Registration Statement, the Time of Sale Prospectus, any broadly available road show or the Prospectus based upon information furnished to the Company in writing by any Underwriter through the Managers expressly for use therein, it being understood and agreed that the only such information furnished by or on behalf of any Underwriter consists of the information described as such in Section 8(b) hereof or (y) that part of the Registration Statement that constitutes the Statement of Eligibility (Form T-1) under the Trust Indenture Act, of the Trustee.

(j) (i) The Securities have been duly authorized by the Company and, when issued and delivered and paid for by the Underwriters in accordance with the terms of this Agreement, will have been duly executed, authenticated, issued and delivered and will constitute valid and legally binding obligations of the Company, enforceable against the Company in accordance with their terms, subject to the effects of applicable bankruptcy, insolvency, reorganization and other laws of general applicability relating to or affecting creditors’ rights and to general equitable principles, entitled to the benefits provided by the Indenture under which they are to be issued, which will be substantially in the form previously delivered to you; and (ii) the Guarantees have been duly authorized by the Guarantors and, when the Securities have been executed, authenticated and issued in accordance with the provisions of the Indenture and delivered to and paid for by the Underwriters in accordance with the terms of this Agreement, the Guarantees will be the valid and legally binding obligations of the Guarantors, enforceable against the Guarantors in accordance with their terms, subject to the effects of applicable bankruptcy, insolvency, reorganization and other laws of general applicability relating to or affecting creditors’ rights and to general equitable principles.

the Prospectus, individually or in the aggregate have had or are reasonably likely to result in a Material Adverse Effect, and to Covidien plc’s knowledge, neither the Company nor any Guarantor has received any written indication that any such proceedings are threatened or contemplated by governmental authorities or threatened by others, or (ii) that are required to be described in the Registration Statement or the Prospectus and are not so described; and there are no statutes, regulations, contracts or other documents that are required to be described in the Registration Statement or the Prospectus or to be filed as exhibits to the Registration Statement that are not described or filed as required.

(s) Since the date of the latest audited consolidated financial statements included in the Time of Sale Prospectus and the Prospectus, there has been no change in internal control over the consolidated financial reporting of Covidien plc that has materially affected, or is reasonably likely to materially affect, the internal control over the consolidated financial reporting of Covidien plc.

reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles (“GAAP”) and to ensure the accuracy of the interactive data in eXtensible Business Reporting Language included or incorporated by reference in the Registration Statement. Except as disclosed in the Time of Sale Prospectus, (i) the internal control over consolidated financial reporting of Covidien plc is effective, and (ii) Covidien plc is not aware of any material weaknesses in its internal control over financial reporting.

(w) Covidien plc is subject to Section 13 or 15(d) of the Exchange Act.

(x) Neither the Company nor any of the Guarantors is in violation of its charter or other governing documents or its by-laws.

(y) Neither the Company nor any Guarantor is in default in the performance or observance of any obligation, agreement, covenant or condition contained in any indenture, mortgage, deed of trust, loan agreement, lease or other agreement or instrument to which it is a party or by which it or any of its properties may be bound, which default has had or is reasonably likely to result in a Material Adverse Effect.

(z) The statements set forth in the Time of Sale Prospectus and the Prospectus under the captions “Description of Debt Securities,” “Description of Notes,” insofar as they purport to describe the material terms of the Securities and the Guarantees, and the statements set forth in the Time of Sale Prospectus and the Prospectus under the captions “Plan of Distribution” and “Underwriting,” insofar as they purport to describe the material provisions of the laws and documents referred to therein, fairly describe, in all material respects, those terms and provisions.

(aa) To the extent that the statements set forth in the Time of Sale Prospectus and the Prospectus under the captions “Certain Luxembourg, Bermuda and Ireland Tax Considerations” and “Certain United States Federal Income Tax Consequences” purport to describe certain provisions of the tax laws referred to therein, such summaries fairly describe, in all material respects, such provisions.

Each Underwriter severally covenants with the Company and the Guarantors not to take any action that would result in the Company or the Guarantors being required to file with the Commission under Rule 433(d) a free writing prospectus prepared by or on behalf of any Underwriter that otherwise would not be required to be filed by the Company or the Guarantors thereunder, but for the action of the Underwriter.

8. Indemnity and Contribution. (a) The Company and the Guarantors, jointly and severally, agree to indemnify and hold harmless each Underwriter, each person, if any, who controls any Underwriter within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act and each affiliate of any Underwriter within the meaning of Rule 405 under the Securities Act from and against any and all losses, claims, damages and liabilities (including, without limitation, any legal or other expenses reasonably incurred in connection with defending or investigating any such action or claim) caused by or based upon any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or any amendment thereto, any preliminary prospectus, the Time of Sale Prospectus, the Prospectus, any issuer free writing prospectus as defined in Rule 433(h) under the Securities Act, the final term sheet required to be prepared and filed pursuant to Section 6(l) hereto or any amendment or supplement thereto, any Company or Guarantors’ information that the Company or Guarantors have filed, or are required to file, pursuant to Rule 433(d) under the Securities Act or the Prospectus or any amendment or supplement thereto, or caused by any omission or alleged omission to state in (A) the Registration Statement or any amendment thereto, any material fact required to be stated therein or necessary to make the statements therein not misleading, or (B) any preliminary prospectus, the Time of Sale Prospectus, the Prospectus, any issuer free writing prospectus as defined in Rule 433(h) under the Securities Act, the final term sheet required to be prepared and filed pursuant to Section 6(l) hereto or any amendment or supplement thereto, any material fact necessary in order to make the statements therein, in light of the circumstances in which they were made, not misleading, in each case, except insofar as such losses, claims, damages or liabilities are caused by any such untrue statement or omission or alleged untrue statement or omission based upon information furnished to the Company and the Guarantors in writing by any Underwriter through you expressly for use therein, it being understood and agreed that the only such information furnished by or on behalf of any Underwriter consists of the information described as such in Section 8(b) hereof.

(b) Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless the Company and the Guarantors, their directors, their officers who sign the Registration Statement and each person, if any, who controls the Company or the Guarantors within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act to the same extent as the foregoing indemnity from the Company and the Guarantors to any Underwriter, but only with reference to information furnished to the Company or the Guarantors in writing by any Underwriter through you expressly for use in the Registration Statement, any preliminary prospectus, the Time of Sale Prospectus, any issuer free writing prospectus or the Prospectus or any amendment or supplement thereto. The Company acknowledges that the statements set forth in (i) the last paragraph of the cover page regarding delivery of the Securities, (ii) the table of Underwriters and their respective participation in the sale of the Securities under the caption “Underwriting,” (iii) the two sentences relating to concessions and reallowances in the third paragraph under the caption “Underwriting” and (iv) the two paragraphs under the caption “Underwriting—Price Stabilization and Short Positions” in any preliminary prospectus, the Time of Sale Prospectus and the Prospectus constitute the only information furnished in writing by or on behalf of the several Underwriters for inclusion in the Registration Statement, any preliminary prospectus, the Time of Sale Prospectus, any issuer free writing prospectus or the Prospectus or any amendment or supplement thereto.

(c) In case any proceeding (including any governmental investigation) shall be instituted involving any person in respect of which indemnity may be sought pursuant to Section 8(a) or 8(b), such person (the “indemnified party”) shall promptly notify the person against whom such indemnity may be sought (the “indemnifying party”) in writing and the indemnifying party, upon request of the indemnified party, shall retain counsel reasonably satisfactory to the indemnified party to represent the indemnified party and any others the indemnifying party may designate in such proceeding and shall pay the reasonably incurred fees and disbursements of such counsel related to such proceeding. In any such proceeding, any indemnified party shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such indemnified party unless (i) the indemnifying party and the indemnified party shall have mutually agreed to the retention of such counsel or (ii) the named parties to any such proceeding (including any impleaded parties) include both the indemnifying party and the indemnified party and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. It is understood that the indemnifying party shall not, in respect of the legal expenses of any indemnified party in connection with any proceeding or related proceedings in the same jurisdiction, be liable for the fees and expenses of more than one separate firm (in addition to

any local counsel) for all such indemnified parties and that all such fees and expenses shall be reimbursed as they are incurred. Such firm shall be designated in writing by the Manager authorized to appoint counsel under this Section set forth in Schedule I hereto, in the case of parties indemnified pursuant to Section 8(a), and by the Company and the Guarantors, in the case of parties indemnified pursuant to Section 8(b). The indemnifying party 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 from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel as contemplated by the second and third sentences of this paragraph, the indemnifying party agrees that it shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 45 days after receipt by such indemnifying party of the aforesaid request and (ii) such indemnifying party shall not have reimbursed the indemnified party in accordance with such request prior to the date of such settlement. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened proceeding in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party, unless such settlement (i) includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such proceeding and (ii) does not include a statement as to or an admission of fault, culpability, guilt or a failure to act by or on behalf of any indemnified party.

(d) To the extent the indemnification provided for in Section 8(a) or 8(b) is unavailable to an indemnified party or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then each indemnifying party under such paragraph, in lieu of indemnifying such indemnified party thereunder, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (i) in such proportion as is appropriate to reflect the relative benefits received by the Company and the Guarantors on the one hand and the Underwriters on the other hand from the offering of the Securities or (ii) if the allocation provided by clause 8(d)(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 8(d)(i) above but also the relative fault of the Company and the Guarantors on the one hand and of the Underwriters on the other hand in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative benefits received by the Company and the

Guarantors on the one hand and the Underwriters on the other hand in connection with the offering of the Securities (and the related Guarantees) shall be deemed to be in the same respective proportions as the net proceeds from the offering of the Securities (before deducting expenses) received by the Company and the Guarantors and the total underwriting discounts and commissions received by the Underwriters bear to the aggregate initial public offering price of the Securities as set forth in the Prospectus. The relative fault of the Company and the Guarantors on the one hand and the Underwriters on the other hand shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company and the Guarantors or by the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Underwriters’ respective obligations to contribute pursuant to this Section 8 are several in proportion to the respective principal amounts of Securities they have purchased hereunder, and not joint.

(e) The Company, the Guarantors and the Underwriters agree that it would not be just or equitable if contribution pursuant to this Section 8 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 that does not take account of the equitable considerations referred to in Section 8(d). The amount paid or payable by an indemnified party as a result of the losses, claims, damages and liabilities referred to in Section 8(d) shall be deemed to include, subject to the limitations set forth above, any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 8, no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Securities underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages that any Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. 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 remedies provided for in this Section 8 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any indemnified party at law or in equity.

9. Effectiveness; Defaulting Underwriters. This Agreement shall become effective upon the execution and delivery hereof by the parties hereto.

If, on the Closing Date, any one or more of the Underwriters shall fail or refuse to purchase Securities that it has or they have agreed to purchase hereunder on such date, and the aggregate principal amount of Securities which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase is not more than one-tenth of the aggregate principal amount of the Securities to be purchased on such date, the other Underwriters shall be obligated severally in the proportions that the principal amount of Securities set forth opposite their respective names in Schedule II bears to the aggregate principal amount of Securities set forth opposite the names of all such non-defaulting Underwriters, or in such other proportions as you may specify, to purchase the Securities which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase on such date; provided that in no event shall the principal amount of Securities that such Underwriter has agreed to purchase pursuant to this Agreement be increased pursuant to this Section 9 by an amount in excess of one-ninth of such principal amount of Securities without the written consent of such Underwriter. If, on the Closing Date, any Underwriter or Underwriters shall fail or refuse to purchase Securities and the aggregate principal amount of Securities with respect to which such default occurs is more than one-tenth of the aggregate principal amount of Securities to be purchased on such date, and arrangements satisfactory to you, the Company and the Guarantors for the purchase of such Securities are not made within 36 hours after such default, this Agreement shall terminate without liability on the part of any non-defaulting Underwriter or the Company or the Guarantors. In any such case either you 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, in the Registration Statement, in the Time of Sale Prospectus, in the Prospectus or in any other documents or arrangements may be effected. Any action taken under this paragraph shall not relieve any defaulting Underwriter from liability in respect of any default of such Underwriter under this Agreement.

10. Reimbursement of Underwriters’ Expenses. If (a) this Agreement shall be terminated by the Underwriters, or any of them, because of any failure or refusal on the part of the Company or the Guarantors to comply with the terms or to fulfill any of the conditions of this Agreement, (b) the sale of the Securities provided for herein is not consummated because any condition to the obligations of the Underwriters set forth in Section 5 hereof is not satisfied, or (c) for any reason the Company or the Guarantors shall be unable to perform their respective obligations under this Agreement, then in each such case, the Company and the Guarantors, jointly and severally, shall reimburse the Underwriters or such Underwriters as have so terminated this Agreement with respect to themselves, as the case may be, severally, for all out-of-pocket expenses (including the fees and disbursements of their counsel) reasonably incurred by such Underwriters in connection with this Agreement or the offering contemplated hereunder.

11. Entire Agreement. (a) This Agreement, together with any contemporaneous written agreements and any prior written agreements (to the extent not superseded by this Agreement) that relate to the offering of the

Securities (and the related Guarantees), represents the entire agreement between the Company, the Guarantors and the Underwriters with respect to the preparation of any preliminary prospectus, the Time of Sale Prospectus, the Prospectus, the conduct of the offering, and the purchase and sale of the Securities.

(b) The Company and the Guarantors acknowledge that in connection with the offering of the Securities (and the related Guarantees): (i) the Underwriters have acted at arms length, are not agents of, and owe no fiduciary duties to, the Company, the Guarantors or any other person, (ii) the Underwriters owe the Company and the Guarantors only those duties and obligations set forth in this Agreement and prior written agreements (to the extent not superseded by this Agreement), if any, and (iii) the Underwriters may have interests that differ from those of the Company or the Guarantors. The Company and the Guarantors waive to the full extent permitted by applicable law any claims it may have against the Underwriters arising from an alleged breach of fiduciary duty in connection with the offering of the Securities.

12. Counterparts. This Agreement may be signed in two or more counterparts, each of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument.

13. Applicable Law. This Agreement and any claim, controversy or dispute arising under or related to this Agreement shall be governed by and construed in accordance with the laws of the State of New York.

14. Headings. The headings of the sections of this Agreement have been inserted for convenience of reference only and shall not be deemed a part of this Agreement.

15. Notices. All communications hereunder shall be in writing and effective only upon receipt and if to the Underwriters shall be delivered, mailed or sent to you at the address set forth in Schedule I hereto; and if to the Company or the Guarantors shall be delivered, mailed or sent to the address set forth in Schedule I hereto.

16. USA Patriot Act. In accordance with the requirements of the USA Patriot Act, the Underwriters are required to obtain, verify and record information that identifies their respective clients, including the Company and the Guarantors, which information may include the name and address of their respective clients, as well as other information that will allow the Underwriters to properly identify their respective clients.

17. Jurisdiction. Each of the Company and the Guarantors irrevocably submits to the non-exclusive jurisdiction of any New York State or United States Federal court sitting in The City of New York over any suit, action or proceeding arising out of or relating to this Agreement. Each of the Company and the

Guarantors irrevocably waives, to the full extent permitted by law, any objection which it may now or hereafter have to the laying of venue of any such suit, action or proceeding brought in such a court and any claim that any such suit, action or proceeding brought in such a court has been brought in an inconvenient forum. To the extent that the Company or the Guarantors has or hereafter may acquire any immunity (on the grounds of sovereignty or otherwise) from the jurisdiction of any court or from any legal process with respect to itself or its property, each of the Company and the Guarantors irrevocably waives, to the full extent permitted by law, such immunity in respect of any such suit, action or proceeding. Each of the Company and the Guarantors hereby irrevocably appoints CT Corporation System, with offices at 000 Xxxxxx Xxxxxx, Xxx Xxxx, Xxx Xxxx 00000, as its agent for service of process in any suit, action or proceeding described in the preceding paragraph and agrees that service of process in any such suit, action or proceeding may be made upon it at the office of such agent. Each of the Company and the Guarantors waives, to the full extent permitted by law, any other requirements of or objections to personal jurisdiction with respect thereto. Each of the Company and the Guarantors represents and warrants that such agent has agreed to act as its agent for service of process, and each of the Company and the Guarantors agrees to take any and all action, including the filing of any and all documents and instruments, that may be necessary to continue such appointment in full force and effect.

18. Waiver of Jury Trial. THE COMPANY AND EACH GUARANTOR HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY.

19. Currency Indemnity. If for the purposes of obtaining judgment in any court it is necessary to convert a sum due hereunder into any currency other than United States dollars, the parties hereto agree, to the fullest extent permitted by law, that the rate of exchange used shall be the rate at which in accordance with normal banking procedures the Underwriters could purchase United States dollars with such other currency in The City of New York on the business day preceding that on which final judgment is given. The obligation of the Company and the Guarantors with respect to any sum due from either of them to such Underwriter or any person controlling such Underwriter shall, notwithstanding any judgment in a currency other than United States dollars, not be discharged until the first business day following receipt by such Underwriter or controlling person of such Underwriter of any sum in such other currency, and only to the extent that such Underwriter or controlling person of such Underwriter may in accordance with normal banking procedures purchase United States dollars with such other currency. If the United States dollars so purchased are less than the sum originally due to such Underwriter or controlling person of such Underwriter hereunder, the Company and the Guarantors jointly and severally agree, as a separate obligation and notwithstanding any such judgment, to indemnify such

Underwriter or controlling person of such Underwriter against such loss.
