This PERFORMANCE GUARANTY (as amended, supplemented or otherwise modified from time to time, this “Performance Guaranty”),
dated as of July 28, 2014, is made by MALLINCKRODT INTERNATIONAL FINANCE S.A., a public limited liability company (société anonyme) organized under the laws of the Grand Duchy of Luxembourg having its registered office at
42-44, avenue de la Gare, L-1601 Luxembourg and registered with the Luxembourg Trade and Companies Register under number B 172.865 (the “Performance Guarantor”), in favor of PNC BANK, NATIONAL ASSOCIATION, as administrative agent
(together with its successors and assigns in such capacity, the “Administrative Agent”), for the benefit of itself, the Purchasers and their respective successors and assigns under the Note Purchase Agreement (as defined below).
Capitalized terms used, but not otherwise defined herein shall have the respective meanings assigned thereto in the Note Purchase Agreement referred to below or, if not defined therein, the respective meanings assigned thereto in the Purchase and
Sale Agreement (as defined below). 
 PRELIMINARY STATEMENTS: 

(1) Concurrently herewith, Mallinckrodt Securitization S.à r.l., a public limited liability company (société à
responsabilité limitée) incorporated under the laws of the Grand Duchy of Luxembourg (the “SPV”), as buyer, Mallinckrodt LLC (“Mallinckrodt”), as initial servicer (in such capacity, together with
its successor and assigns in such capacity, the “Servicer”), and the various other entities party thereto as originators are entering into that certain Purchase and Sale Agreement, dated as of the date hereof (as amended, restated,
supplemented or otherwise modified from time to time, the “Purchase and Sale Agreement”). Each entity from time to time party to the Purchase and Sale Agreement as an originator thereunder is herein referred to as an
“Originator” and, collectively, as the “Originators”. Pursuant to the Purchase and Sale Agreement, the Originators will from time to time sell Receivables and Related Rights to the SPV. 

(2) Concurrently herewith, the SPV, as issuer, Mallinckrodt, as initial Servicer, the Persons from time to time party thereto as Purchasers
and the Administrative Agent are entering into that certain Note Purchase Agreement, dated as of the date hereof (as amended, restated, supplemented or otherwise modified from time to time, the “Note Purchase Agreement”), pursuant
to which (i) the Purchasers will from time to time make Advances to the SPV on a revolving basis, (ii) the SPV has granted to the Administrative Agent (on behalf of the Secured Parties) a security interest in the Collateral and
(iii) Mallinckrodt, as Servicer, will service the Pool Receivables. 
 (3) As of the date hereof, the Performance Guarantor is the
direct or indirect owner of 100% of the outstanding Capital Stock of Mallinckrodt, the Servicer, each Originator and the SPV. 
 (4) The
Performance Guarantor’s execution and delivery of this Performance Guaranty are conditions precedent to the effectiveness of the Note Purchase Agreement. 







 (5) The Performance Guarantor has determined that its execution and delivery of this Performance
Guaranty is in its best interests because, inter alia, the Performance Guarantor (individually) and the Performance Guarantor and its Affiliates (collectively) will derive substantial direct and indirect benefit from (i) each
Originator’s sales of Receivables to the SPV from time to time, (ii) the Servicer’s servicing of the Receivables, (iii) the financial accommodations made by the Purchasers to the SPV from time to time under the Note Purchase
Agreement and (iv) the other transactions contemplated under the Purchase and Sale Agreement and the Note Purchase Agreement. 
 NOW,
THEREFORE, for good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the Performance Guarantor hereby agrees as follows: 

SECTION 1. Unconditional Undertaking; Enforcement. The Performance Guarantor hereby unconditionally and irrevocably undertakes and
assures for the benefit of the Administrative Agent (including, without limitation, as assignee of the SPV’s rights, interests and claims under the Purchase and Sale Agreement), the Purchasers and each of the other Secured Parties the due and
punctual performance and observance by Mallinckrodt, the Servicer and each Originator (together with their respective successors and assigns, collectively, the “Covered Entities”, and each, a “Covered Entity”) of
the terms, covenants, indemnities, conditions, agreements, undertakings and obligations on the part of such Covered Entity to be performed or observed by it under the Purchase and Sale Agreement and each of the other Transaction Documents to which
such Covered Entity is a party, including, without limitation, any agreement or obligation of such Covered Entity to pay any indemnity or make any payment in respect of any applicable dilution adjustment or repurchase obligation under any such
Transaction Document, in each case on the terms and subject to the conditions set forth in the applicable Transaction Documents as the same shall be amended, restated, supplemented or otherwise modified and in effect from time to time (all such
terms, covenants, indemnities, conditions, agreements, undertakings and obligations on the part of the Covered Entities to be paid, performed or observed by them being collectively called the “Guaranteed Obligations”). Without
limiting the generality of the foregoing, the Performance Guarantor agrees that if any Covered Entity shall fail in any manner whatsoever to perform or observe any of its Guaranteed Obligations when the same shall be required to be performed or
observed under any applicable Transaction Document, then the Performance Guarantor will itself duly and punctually cause to be performed or observed such Guaranteed Obligations. It shall not be a condition to the accrual of the obligation of the
Performance Guarantor hereunder to cause to be performed or observed any Guaranteed Obligation that the Administrative Agent, any Purchaser, the SPV or any other Person shall have first made any request of or demand upon or given any notice to the
Performance Guarantor, any Covered Entity or any of their respective successors and assigns or have initiated any action or proceeding against the Performance Guarantor, any Covered Entity or any of their respective successors and assigns in respect
thereof. The Administrative Agent (on behalf of itself, the Purchasers and the other Secured Parties) may proceed to enforce the obligations of the Performance Guarantor under this Performance Guaranty without first pursuing or exhausting any right
or remedy which the Administrative Agent or any Purchaser may have against any Covered Entity, the SPV, any other Person, the Pool Receivables or any other property. The Performance Guarantor agrees that its obligations under this Performance
Guaranty shall be irrevocable. It is expressly acknowledged that this Performance Guaranty is a guarantee of performance only and is not a guarantee of the payment of any Pool Receivables 

  
 2 








 
and there shall be no recourse to the Performance Guarantor for any non-payment or delay in payment of any Pool Receivables solely by reason of the bankruptcy, insolvency or lack of
creditworthiness of the related Obligor or the uncollectability of any such Pool Receivables or for any Guaranteed Obligations the payment of which could otherwise constitute recourse to the Performance Guarantor or any Covered Entity for
uncollectible Pool Receivables. 
 SECTION 2. Validity of Obligations. 

(a) The Performance Guarantor agrees that its obligations under this Performance Guaranty shall be absolute and unconditional,
irrespective of (i) the validity, enforceability, avoidance, subordination, discharge or disaffirmance by any Person (including a trustee in bankruptcy) of the Guaranteed Obligations, (ii) the absence of any attempt by the Administrative
Agent, any Purchaser or the SPV to collect any Receivables, or to obtain performance or observance of the Guaranteed Obligations from any Covered Entity or any other Person, (iii) the waiver, consent, amendment, modification, extension,
forbearance or granting of any indulgence by the Administrative Agent, any Purchaser or the SPV with respect to any provision of any agreement or instrument evidencing the Guaranteed Obligations, (iv) any change of the time, manner or place of
performance of, or in any other term or provision of any of the Guaranteed Obligations, including, without limitation, any amendment to or modification of any of the Transaction Documents, (v) any law, rule, regulation or order of any
jurisdiction affecting any term of any of the Guaranteed Obligations, or rights of the Administrative Agent, any Purchaser or the SPV with respect thereto, (vi) the failure by the Administrative Agent, any Purchaser or the SPV to take any steps
to perfect and maintain perfected its interest in any Receivable, the Collateral or any portion thereof or other property or in any security or collateral related to the Guaranteed Obligations, (vii) any failure to obtain any authorization or
approval from or other action by or to notify or file with, any Governmental Authority required in connection with the performance of the obligations hereunder by the Performance Guarantor, (viii) any impossibility or impracticability of
performance, illegality, force majeure, any act of government, or other circumstances which might constitute a defense available to, or a discharge of any Covered Entity or the Performance Guarantor, or any other circumstance, event or
happening whatsoever whether foreseen or unforeseen and whether similar to or dissimilar to anything referred to above, (ix) any manner of application of Collateral or any assets of any Covered Entity or the SPV, or proceeds thereof, to satisfy
all or any of the Guaranteed Obligations or as otherwise permitted under the Transaction Documents, or any manner of sale or other disposition of any Collateral for all or any of the Guaranteed Obligations or as otherwise permitted under the
Transaction Documents and (x) any change, restructuring or termination of the corporate structure or existence of any Covered Entity, the Performance Guarantor or any other Person or the equity ownership, existence, control, merger,
consolidation or sale, lease or transfer of any of the assets of any such Person, or any bankruptcy, insolvency, winding up, dissolution, liquidation, receivership, assignment for the benefit of creditors, arrangement, composition, readjustment or
reorganization of, or similar proceedings affecting, any Covered Entity, the SPV or any of their assets or obligations. The Performance Guarantor waives all set-offs and counterclaims and all presentments, demands of performance, notices of
nonperformance, protests, notices of protest, notices of dishonor and notices of 

  
 3 








 
acceptance of this Performance Guaranty. The Performance Guarantor’s obligations under this Performance Guaranty shall not be limited if the Administrative Agent or any Purchaser is
precluded for any reason (including, without limitation, the application of the automatic stay under Section 362 of the Bankruptcy Code) from enforcing or exercising any right or remedy with respect to the Guaranteed Obligations, and the
Performance Guarantor shall perform or observe, upon demand, the Guaranteed Obligations that could otherwise have been due and performable or observable by any Covered Entity had such right and remedies been permitted to be exercised. 

(b) Should any money due or owing under this Performance Guaranty not be recoverable from the Performance Guarantor due to any
of the matters specified above in Section 2(a), then, in any such case, such money shall nevertheless be recoverable from the Performance Guarantor as though the Performance Guarantor were a principal debtor in respect thereof and not
merely a guarantor and shall be paid by the Performance Guarantor forthwith. 
 SECTION 3. Reinstatement, etc. The Performance
Guarantor further agrees that, to the extent that any Person makes a payment or payments to the Administrative Agent or any Purchaser in respect of any Guaranteed Obligation, which payment or payments or any part thereof are subsequently
invalidated, declared to be fraudulent or preferential, set aside and/or required to be repaid to such Person or to the estate, trustee, or receiver of such Person or to any other party, including, without limitation, the Performance Guarantor,
under any bankruptcy, insolvency or similar state or federal law, common law or equitable cause, then, to the extent of such payment or repayment, the Guaranteed Obligations or any part thereof which has been paid, reduced or satisfied by such
amount shall be reinstated and continued in full force and effect as of the date such initial payment, reduction or satisfaction occurred. 

SECTION 4. Waiver. The Performance Guarantor hereby waives promptness, diligence, notice of acceptance, notice of default by the
Covered Entities, notice of the incurrence of any Guaranteed Obligation and any other notice with respect to any of the Guaranteed Obligations and this Performance Guaranty, and any other document related thereto or to any of the Transaction
Documents and any requirement that the Administrative Agent, any Purchaser or the SPV exhaust any right or take any action against any Covered Entity, the SPV, any other Person or any property. The Performance Guarantor acknowledges to the
Administrative Agent (for the benefit of itself, the Purchasers and the other Secured Parties) that it is not relying on the Administrative Agent, any Group Agent or any Purchaser to provide any information with respect to any Covered Entity and the
SPV either now or in the future. 
 SECTION 5. Subrogation. The Performance Guarantor hereby waives all rights of subrogation
(whether contractual or otherwise) to the claims, if any, of the Administrative Agent or any Purchaser against the Originators and all contractual, statutory or common law rights of reimbursement, contribution or indemnity from the Covered Entities
which may otherwise have arisen in connection with this Performance Guaranty until one year and one day have elapsed since the payment and performance in full of all Guaranteed Obligations.
